Thanks, I'll reassign the bug to the 3D driver. Unfortunately, upstream
does not support it¹, but hopefully there will be a backport of a later
Mesa version to Wheezy some day.
For now, if you intend to play 3D games you will have to install the
xserver-xorg-video-nvidia-legacy-173xx package from non-free, but for 2D
nouveau should be good enough.
Cheers,
Sven
