Short description of error
I simply switched to texture paint mode,clicked on a mesh(cube with uv's or anywhere in the scene view) to paint and blender closed itself(crashed but didn't stop responding,window closed).
version is from here: http://graphicall.org/1055 (file too big to upload!)
Exact steps for others to reproduce the error
Just download built and try to paint(if it will happen to you).
I'm not sure that .blend will help you.
