OK, looks like another Intel graphics bug, windows 7 + NVIDIA 540 works well, It may be worth an investigation if get the time to do it.

In fact, ubuntu + NVIDIA drivers works fine, so it's definitely an Intel case. I did a debugging session and found that around the crash, all VBO related values are sane. Definitely a driver bug then.

I'll copy this over to the opengl tracker then, to keep history. Too bad Intel lets us down once again.

Moved from Blender 2.5 Bug Tracker to OpenGL errors

I can confirm that with Blender 2.65a and 2.66RC that I get Blender crashes (segmentation fault) when I select objects. Running Ubuntu 12.10.

I had to reset my startup Blend file to isolate what was going on. I found out that enabling VBOs in 'User Preferences' is causing the crashes on my HD Graphics 4000 graphics card.

So it looks like this will be the first bug I will try and tackle, since it's a major issue for me. It looks like it's an Intel integrated graphics issue.

I'm using Mesa hardware accelerated graphics drivers. Mesa 9.2-devel, OpenGL 3.0.

I will try to see if it's a problem in the drivers or if it's something that we can fix in Blender code to make it work.
