- Confirmed 1). It appears GLSL and preview render is accessing the material nodes at the same time giving issues.
Also can confirm 2), there's another report about this in the tracker, basically VBO don't do editmode drawing correctly.

- Lukas, do you think you can look into these VBO bugs? I've fixed a few but don't want to spend time on this, there's 5 bugs in the tracker now, and it seems not stable enough for day to day use at the moment.

- It seems this bug isn't VBO related anymore, renamed it and assigned to self.

- Brecht: I can work on material/texture nodes to not share same data, but the crash log doesnt give me a real clue (see below). Maybe just because memfree bad access?

- I'm seeing a different crash, backtrace below, it's thread 6 that crashed. Both glsl and preview render seem to be reading/writing the same node stack memory.

- OK good find, let's see if I can make a full material copy before passing it on the preview render.

- I've made previews copy materials on render, gives stable results for the test file.
