Bug#410386: Xorg segfaults randomly
OK, ran it for a few hours and finally got a BT, I don't think this is
very informative though, which package contains the Debugging Symbols?
Or should I run Xorg in a special way?
I used the following docs to understand what to do:
http://xorg.freedesktop.org/wiki/DebuggingTheXserver
but to my naked eye, it seems like there are no debugging symbols.

Can you try to attach gdb to the X server and get a full backtrace?
