Status changed to 'Confirmed' because the bug affects multiple users.

[Jeronimo Paoletti (jeronimo-paoletti)]

I got this error after uninstalling fglxr package. After reinstalling it, everything is back to a normal state.

[Angel Guzman Maeso (shakaran)]

I get the same error uninstalling fglxr and running glxinfo, steps for reproduce:

sudo apt-get purge xorg-driver-fglrx fglrx-*
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri
sudo dpkg-reconfigure xserver-xorg
sudo apt-get install --reinstall xserver-xorg-core

Then run:

glxinfo

This crash will appear.
