System Information
Windows 7 64-bit
Intel HD Graphics 4000

Blender Version
Broken: 2.69 r60995, 2.70 19e627c, 2.71 9337574, 2.72rc eb464ee
Worked: 2.67 r56533 2.68a r58537

Files
crash.blend - Contains an Empty in the active layer that has the following script:

import bge

for i in range(3):
    print('LibNew:', i)
    bge.logic.LibNew('New', 'Mesh', ['Plane'])
    print('LibFree:', i)
    bge.logic.LibFree('New')

There is a Plane on the inactive layer that is using the default material.

Description
The BGE crashes after calling LibFree twice on objects that have a material attached.

Exact steps for others to reproduce the error
Open crash.blend. Press P to start the BGE. Blender will immediately crash after printing the following to the console:

LibNew: 0
LibFree: 0
LibNew: 1
LibFree: 1

This shows the crash occurs at the second call to LibFree.

Additional Notes

The calls to LibNew/LibFree do not have to happen on the same frame for the crash to occur.
Changing the name of the library each loop has no effect
Changing the mesh/material that LibNew/LibFree is called on each loop has no effect. The only requirement is that the objects have a material
It does not matter if the object passed to LibNew is on an active or inactive layer.
The crash happens on both Multitexture and GLSL shading modes.
