System Information
Xubuntu 64 14.04 - AMD HD5450 (sys info attached)

Blender Version
Broken: 2.73 (built with debug options from latest sources)

Short description of error
Alternating calls to bge.logic.LibLoad (synchronous) - bge.logic.LibFree generates a SIGSEGV. On my system, the signal is always generated at (GDB):

0 0x0000000008f3c310 in ?? ()
1 0x0000000002e9044e in operator== (rhs=..., lhs=...) at /home/pgi/blender-dev/blender/source/gameengine/Rasterizer/RAS_IPolygonMaterial.h:200

2 0x0000000002e8f9aa in RAS_BucketManager::FindBucket (this=0x6d19980, material=0x8123280, bucketCreated=@0x7fffffffac9e: false)

  at /home/pgi/blender-dev/blender/source/gameengine/Rasterizer/RAS_BucketManager.cpp:262

3 0x0000000002e0659d in KX_Scene::FindBucket (this=0x8f841b0, polymat=0x8123280, bucketCreated=@0x7fffffffac9e: false) at /home/pgi/blender-dev/blender/source/gameengine/Ketsji/KX_Scene.cpp:1726

Exact steps for others to reproduce the error
unzip, open "mainfile.blend", press P, wait for SIGSEGV (can take some cycles, always happens).

I have included two stack traces from the debugger in the zip. There might be something fishy going on with materials mistakenly kept in the bucket after a LibFree but I haven't been able to find out what.
