**System Information**
Microsoft Windows 7 32-bit
4 GB RAM
NVidia GeForce 580 Ti
**Blender Version**
Broken: Blender 2.69.0 r60995
Crashes with previous stable version (2.68) too.
**Short description of error**
Every second time I try to render the scene, Blender crashes.
**Exact steps for others to reproduce the error**
Open the attached Blender scene. Render it, then render it again. The second time you are trying to render the scene, Blender crashes.
Since I have trouble to upload the files to this report in Opera, download the .blend file from here:

This error is not easy to repeat. Sometimes Blender renders the scene correctly a few times and then then crashes.
I've tapped into the Blender with Visual Studio and cought the exception. The details follows:

**Minidump with heap**
I've saved the minidump file from the crash. You can access it here:
http://www.spook.freshsite.pl/Temporary/Blender/blender.dmp (It should be available ~30 mins from posting this report, weighs around 700 Mb).
If you provide me with the debugging symbols for the stable version (Blender 2.69.0 r60995), I may try to post the resolved call stack.
