<pre>Hi, this is an old bug we are encountering in blender.
My system is Ubuntu 12.10, Intel® Core™ i5-2410M CPU @ 2.30GHz × 4, 4GB ram,
Hybrid NVIDIA GT 540M - Intel(R) Sandybridge Mobile
To reproduce,
* start blender
* enable VBO in user preferences (Ctrl-Alt-U) under the system tab.
* try selecting any object on 3D viewport (right clicking on the default Cube
for instance)
My guess is that it has to do with select mode rendering and vertex buffer
object combination. I would do a trunk compile but I am using optimus on my
system and I fear I may destabilize something. If it is safe and would help, I
could attempt it.
The backtrace is:
