Binary package hint: libgl1-mesa-dri

Trying to open the window type selection menue of the main 3D window
right after startup in windowed mode blender crashed 2 out of 2 times.
Put another way: I opened blender, left clicked on the window type
selector and crash.

This is on karmic with xorg-edgers all freshly updated today. 
libgl1-mesa-dri (7.6.0+git20090908.e589a37f-0ubuntu0tormod) to 7.7.0~git20090910.18882f4d-0ubuntu0tormod was part of the upgrade.

Tried to upgrade the other notebook, an acer extensa 5630z: only
upgraded libgl1-mesa-dri from yesterday (20090909) to current (20090910)
xorg-edgers. Same crash. Moreover it does not seem to be too important
what I do to crash it. Mousing over the buttons or trying to open some
menu is enough for a crash.

Extreme Tux Racer is running perfectly fine on both test notebooks.
