Bug 458586

Just to add my experience is exactly the same. Since I updated with yum on Friday 8/8/2008, running system-config-firewall from the command line (or menu option) segfaults:

From cli:
=========

[root@mydomain ~]# system-config-firewall &
[1] 935
[root@mydomain ~]# 
(system-config-firewall.py:940): GLib-GIO-CRITICAL **: g_simple_async_result_set_from_error: assertion `error != NULL' failed
/usr/share/system-config-firewall/fw_gui.py:2149: Warning: g_error_free: assertion `error != NULL' failed
  result = dialog.run()

(system-config-firewall.py:940): GLib-GIO-CRITICAL **: g_simple_async_result_set_from_error: assertion `error != NULL' failed

(system-config-firewall.py:940): GLib-GIO-WARNING **: (gfile.c:5244):IA__g_file_load_partial_contents_finish: runtime check 
failed: (g_simple_async_result_get_source_tag (simple) == g_file_load_contents_async)

[1]+  Exit 139                system-config-firewall
[root@mydomain ~]# 

Extract from /var/log/messages:
===============================
Aug 10 15:20:52 mydomain kernel: system-config-f[940]: segfault at 4 ip 07c73925 sp bfc83b90 error 4 in libgio-2.0.so.0.0.0[7c5b000+6c000]

Now this adds a quirk to the data......

I just happened to have a blank DVD in the DVD drive since mid week (I was getting ready to do a backup and hadn't got round to it yet).

Anyway with the DVD in the drive the bug happens as is, with the DVD out no problem.

Even more interesting if I open a nautilus session (from the root account) and then load a blank DVD the nautilus session segfaults as per the bug.

Couldn't reproduce on clean Fedora 9 system and Rawhide. A stack trace would be really helpful in this case, could you please grab and attach it when crash happens next time? Please also install debug packages of glib2, nautilus and gvfs first. This guide may help you in getting stacktraces: http://fedoraproject.org/wiki/StackTraces

Also, please make sure you have gvfs installed (and verify running via ps aux | grep gvfsd).

Hi Tomáš,

I haven't been able to do a stack trace I'm afraid, but Paul's comment about the blank DVD is worth investigating further.

I too had a blank (well actually not blank but R/W) DVD in the slot ready for my weekly backup.

Removing the DVD allowed it to work.

Putting the DVD into my other F9 system (which worked previously) caused that to segfault too.

So Tomáš, could you try popping a blank (or R/W) DVD in the slot and trying it yourself to see if you can reproduce the error?

p.s.

Without a DVD in the drive I get this:
=======

[root@mydomain ~]# ps aux | grep gvfsd
gdm       2409  0.0  0.2   7232   996 ?        S    Aug10   0:00 /usr/libexec/gvfsd
root     21612  0.0  0.1   5040   704 pts/1    S+   09:36   0:00 grep gvfsd

And system-config-firewall works.


With a DVD in the drive I get this:
====
[root@localhost ~]# ps aux | grep gvfsd
root      1060  0.0  0.0   4120   676 pts/1    R+   09:28   0:00 grep gvfsd
mark      2685  0.0  0.0   6456  1896 ?        S    07:46   0:00 /usr/libexec/gvfsd
mark      2726  0.0  0.1  16992  2476 ?        S    07:46   0:00 /usr/libexec/gvfsd-trash --spawner :1.5 /org/gtk/gvfs/exec_spaw/0
mark      2738  0.0  0.0   6424  1984 ?        S    07:46   0:00 /usr/libexec/gvfsd-burn --spawner :1.5 /org/gtk/gvfs/exec_spaw/1

And system-config-firewall segfaults.

*** Bug 460739 has been marked as a duplicate of this bug. ***

The same bug for me if I run "Open file dialog" in SciTD, gedit or any other programm that uses glib's GIO for it.

Versions of glib are 2.16.3-r1 / glib-2.16.5.

Question to people who see this bug:

Are you using remote X forwarding, with "ssh -X" or "ssh -y"?

If yes, then this is a duplicate of bug 466687 (or vice versa).

No, I am not using remote X forwarding.

I actually have two F9 machines here. One acts as a "headless" server and yes, I *do* ssh into that machine (from the other F9 machine) with a ssh -Y command.

The other F9 machine could be classed as a stand-alone PC (on the same network) i.e. it is not dependent upon the other PC for anything except imap mail feed, a few NFS directories and a couple of other things.

I can confirm that both machines (the one over ssh and the local one) still segfault when given the "system-config-firewall &" command if (and ONLY IF) there is a blank disk in the CD/DVD Drive. Without media in the drive the command works correctly on both machines; with media in the drive the command fails on both machines.

I second comment #10 --- I had a blank DVD in at the time, ejected it and it ran OK.

I was burning a USB-attached DVD+R when I experienced Firefox crashes as follows:

(firefox:29147): GLib-GIO-CRITICAL **: g_simple_async_result_set_from_error: assertion `error != NULL' failed

(firefox:29147): GLib-CRITICAL **: g_error_free: assertion `error != NULL' failed

(firefox:29147): GLib-GIO-CRITICAL **: g_simple_async_result_set_from_error: assertion `error != NULL' failed

(firefox:29147): GLib-GIO-WARNING **: (gfile.c:5249):IA__g_file_load_partial_contents_finish: runtime check failed: (g_simple_async_result_get_source_tag (simple) == g_file_load_contents_async)
/usr/lib64/firefox-3.0.4/run-mozilla.sh: line 131: 29147 Segmentation fault      "$prog" ${1+"$@"}


Firefox was started via opening a terminal, su'ing to another user, and then opening.  Specifically, the crash was triggered during 'open file' related actions.  I'm on a  2.6.26.3 kernel, Firefox 3.0.4, and Fedora 9 with the latest updates as of 18-Nov-2008.

I hope this helps,
George

I guess this bug happens with any kind of user account forwarding, be it ssh -X or su.

Maybe it also happens when some action requires such an elevation-to-root as part of background activity, or maybe act-as-the-group-that-owns-the-dvd?

FYI, I have reported this bug upstream at 
http://bugzilla.gnome.org/show_bug.cgi?id=556458

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 9 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
