gdmgreeter crashed with SIGSEGV in __libc_start_main()

[Chris Pudney]

Binary package hint: gdm

Possible related to the following:

1. gdmgreeter was configured to be "Themed with *face* browser"
2. I use autofs to mount a couple of remote user home directories
    autofs mounts these home directories in /rhome
    I setup up symlinks in /home/foo -> /rhome/foo
3. When gdmgreeter started the remote user directories were unavailable, autofs would have kicked in but not mounted /rhome/foo leaving /home/foo sym-link unresolved

Furthermore,

1. deleting the /home/foo symlink and restarting gdm works
2. configuring gdmgreeter to "Themed" (no *face* browser) works

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

We are closing this bug report as it lacks the information, described in the previous comments, we need to investigate the problem further. However, please reopen it if you can give us the missing information and don't hesitate to submit bug reports in the future.

I was able to reproduce this by switching VTs before GDM was fully loaded.

[Pedro Villavicencio (pedro)]

As Sebastien pointed out we need a backtrace without one the bug is no use.
