Xorg crashed with SIGSEGV

[Per Ångström]

I was logging in (KDM) and was opening the menu to select my session type. Suddenly, the graphic mode was gone and I was in text mode. I had the same crash again when I restarted the computer and went through the same steps. After that, I have not been able to reproduce the crash. I have not seen this crash before, either.

Actually, I think my getting thrown out of KDM was caused by me accidentally hitting ALT+n (console login) instead of ALT+m when trying to activate the KDM menu.

[Robert Hooker (sarvatt)]

Can you reproduce this at all still? I believe this was fixed a few months ago in xorg-server and this bug has fallen through the cracks so I am marking it as fix released, but please change it back to confirmed if that is not the case!
