Bug Description

Not sure what package this belongs to, but libGLcore.so belongs to xserver-xorg-core which is built from xorg-server. I am using the proprietary fglrx driver on an ATI X1300 (RV515).

It crashed again, but not in the same function from what I can see:

I guess the frame 1 at 0xffffe420 which appears in both backtraces is from the crash handling?

Is it interesting that both backtraces start in FontFileCompleteXLFD ?

I have installed xserver-xorg-core-dbgsym and set this in xorg.conf:
Option "NoTrapSignals" "true"
Just have to wait for the next crash :)

Just saw that the second backtrace is the same as in bug #60288. Someone competent has to decide if this is a separate bug or not.
