Public bug reported:

Binary package hint: xserver-xorg

After updating today and rebooting X crashes a few times before dropping
into low-graphics mode. I've saved the logs via the menus there
provided. This is the interesting part:

Backtrace:

Segmentation fault at address 0x100000004

I believe I have the relevant -dbg packages installed, but I don't know
how to make gdm start using those so the backtrace is somewhat useless.
If someone can give instructions for attaching gdb at startup or
otherwise getting a meaningful backtrace I would be grateful.
