Segfault in libGL for glxgears, Blender, Meshlab, visolate, and probably more

[Traumflug]

For a few days now, virtually all applications using OpenGL segfault. For example:

$ glxgears
Segmentation fault
$

Running the same in gdb reveals the following:

Program received signal SIGSEGV, Segmentation fault.

Looks like this library is in the fglrx package.

[Traumflug (mah-jump-ing)]

Got it.

The package emc2-sim depends on fglrx and removing both packages made all OpenGL applications work again.

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