Bug 437061

Do you have the iso-codes package installed?  It doesn't behave very well in
that scenario right now, and the rpm was missing a Requires.

yes it was installed...

it definitely looks like the glib SIGTRAP stuff is tripping it up as although
there may be a bug, the TRAP isn't handled.. hence stracing or gdb let it run
fine as they catch the signal..

Dave, could you install the debuginfo packages for at least gdm, gtk2+, glib2
and try to get a new backtrace?

I had this crash as well, but I tracked it down to something much larger.  I had
been having some trouble with the init socket error problem and ran fixfiles to
try to resolve it.  During that process (perhaps) /tmp's permissions were set to
0755.  When I restored them to 1777 (which I think is the default) gdm prompted
for the password and worked ok.

I had this problem when I first installed F9 yesterday, but after yum updating
this morning I can log in fine. (This is with gdm-2.21.10-0.2008.03.26.1,
although I don't know for sure that it was the gdm fix as opposed to something
else that fixed it.)

Confirming the problem under gdm-2.21.10-0.2008.03.26.3.fc9.i386

The program is running.  Quit anyway (and detach it)? (y or n) [answered Y;
input not from terminal]

Sorry, my bad. The crash didn't go away when I updated, it went away when I
turned off selinux. So I believe the bug is "gdm crashes before password prompt
if selinux is enabled". (I also get a black background and a gnome-power-manager
warning in that case.)

I've had this problem since installing (and also after yum updating) F9 Beta on
Saturday.  I just tried various methods of disabling SELinux and nothing seems
to stop the crashes:

1. echo 1 > /selinux/enforce

2. One at a time as kernel parameters:
enforce=0
and
selinux=0

3. One at a time in /etc/selinux/config:
SELINUX=permissive
and
SELINUX=disabled

I get this after an f8->f9 upgrade.
Obviously my workaround is to boot into runlevel 3 and run "startx".

Also: before the crash I see a message about my energy settings in gnome being
wrong, then my monitor goes to sleep and it won't wake up.

gdm-2.21.10-0.2008.04.03.3.fc9.i386 works fine without disabling selinux.

In /etc/sysconfig/i18n I changed the line:

LANG="="
to
LANG="en_CA.UTF-8"

After rebooting, gdm didn't crash on me anymore and I could actually get to the
desktop.  Yay!  Can anyone confirm this behaviour?

My guess is that Anaconda putting silly things in my i18n config.  However,
shouldn't gdm be able to handle/ignore silly settings like this?

This should be fixed in tomorrows rawhide:

* Sat Apr  5 2008 Ray Strode <rstrode> - 1:2.21.10-0.2008.04.04.1
- Fix jump in animation for autologin
- Fix crash if LANG="somethingbogus"

Where is the list of LANGs that are considered correct?

run system-config-language and pick one there, it should rewrite out the file
for you

LANG="de_AT.UTF-8"
is already correct..

It sounds like you may be experiencing a different issue than Ira.  Can you put
Enable=true in the [debug] section of /etc/gdm/custom.conf, reproduce the crash
and then attach the backtrace in a different bug report?

(you can just click the "Clone as bug" link at the top of this page if you want,
or file a new one from scratch)

gdm no longer crashes since I upgraded today so I am unable to reproduce the
bug, sorry.

oh okay.
