Bug#480056: gdm: Gets killed twice with signal 11 after boot

[Tim Retout]

Package: gdm
Followup-For: Bug #480056

My symptoms are slightly different, but I assume related:

 * gdm crashes on the first two login attempts after each boot.
 * The child crashes of signal 11, not 6. One of the responses to #480469
   mentioned signal 11.

This has been happening since May or so, but other laptop problems got in the
way of my investigating. :)
