Comment 2 Sandro Bonazzola 2010-09-28 09:58:52 UTC
Seen also on F14 with at-spi-1.31.1-3.fc14.i686.
(gdb) bt

set_engine segfault trying to access client->engine with client passed NULL.

Maybe a check on g_object_new result can avoid this. Is it possible that no default client can be found?

Comment 3 Sandro Bonazzola 2010-09-28 10:06:05 UTC
Maybe g_type_init() is just missing.

Created attachment 451003 [details]
Fix missing g_type_init

This fixed the missing call to g_type_init. However, at-spy-registryd exits and doesn't continue to run as daemon.

OK, I can confirm that the patch I've attached fixes the issue on at-spi-1.32.0-1.fc14.i686. The registryd exited because I had /desktop/gnome/interface/at-spi-corba set to false.

It may be that having /desktop/gnome/interface/at-spi-corba set to false is required in order to reproduce this bug.
Could the assignee review the patch and include it in testing?

Comment 7 Sandro Bonazzola 2010-10-19 15:01:46 UTC
Can anybody add the patch created as attachment #451003 [details] to the rpm and push it to testing?

Comment 8 Sandro Bonazzola 2010-11-03 08:24:42 UTC
Reported upstream https://bugzilla.gnome.org/show_bug.cgi?id=633883 .

Comment 9 Sandro Bonazzola 2010-12-01 07:17:42 UTC
Could someone update:
Version: 14
Keyword: Patch Upstream
And add the patch while we are waiting for the next release of at-spi?

Comment 10 Sandro Bonazzola 2010-12-10 13:33:55 UTC
Patch submitted 2 months ago, not yet included in the package.
Is there a reason for the delay?

Comment 11 Sandro Bonazzola 2011-02-01 07:07:48 UTC
Adding Ray Strode to CC as last maintainer working on at-spi-1.32.0-2

Comment 13 Bug Zapper 2011-06-02 11:06:58 UTC
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  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bug reports from releases that are no longer maintained.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 '13'.

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 13'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 13 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

Comment 14 Bug Zapper 2011-06-27 18:05:24 UTC
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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.

Comment 15 Scott Tsai 2012-07-01 12:37:08 UTC
This bug still happens on at-spi-1.32.0-8.fc17.x86_64. Manually run:
/usr/libexec/at-spi-registryd
and you'll see the segfault.
The "Fix missing g_type_init" attached to this bug is still not applied in gnome git master: http://git.gnome.org/browse/at-spi/tree/registryd/registry-main.c#n200

Since /etc/xdg/autostart/at-spi-registryd.desktop contains:
AutostartCondition=GNOME /desktop/gnome/interface/accessibility,
clearing the GConf key "/desktop/gnome/interface/accessibility" stop gnome-session from running at-spi-registryd.

Comment 16 Sandro Bonazzola 2013-03-10 10:24:36 UTC
patch merged upstream: https://git.gnome.org/browse/at-spi/commit/?id=c7639c37ae6ff3456b15adf2cd7ff229e72e4fa0

bug resolved upstream: https://bugzilla.gnome.org/show_bug.cgi?id=633883

Still present in Fedora 18.

Will the patch be included at least for Fedora 19?

Comment 17 Ganapathi Kamath 2013-03-16 23:59:28 UTC
possibly related : 
/var/log/messages contain the following line during boot
Mar 16 19:12:49 localhost kernel: [30655.123618] at-spi-registry[15950]: segfault at 18 ip 0000003017e19911 sp 00007fff058629a0 error 4 in libgconf-2.so.4.1.5[3017e00000+2f000]

I may be wrong but I think 
/usr/libexec/at-spi-registryd
is obsoleting and being replaced by
/usr/libexec/at-spi2-registryd 

at-spi-registry is being killed by signal 11 for some reason. 
and can be easily verified by attempting to start manually from 
cmd line also.

the package installs
/etc/xdg/autostart/at-spi-registryd.desktop

During login, gnome-session waits for 45 seconds(machine subjunctive) before showing desktop waiting for at-spi-registryd to register on dbus after starting it. Making the following allows desktop to be shown in under 10 seconds.    

changing the "Exec=" line in at-spi-registryd.desktop to
Exec=/usr/libexec/at-spi2-registryd 

Potential Resolution in packaging and configuration of at-spi/at-spi2
move /etc/xdg/autostart/at-spi-registryd.desktop
from package at-spi-1.32.0-9.fc18.x86_64
to package at-spi2-core-2.6.3-1.fc18.x86_64
with the above correction. 


at-spi is 
Assistive Technology Service Provider Interface
