%%%When you libLoad a blend file with the 'Scene' type, an overlay scene from the loaded blend, and then libFree the blend blender crashes with:

pure virtual method called
terminate called without an active exception
Aborted

If after the libFree, but before the next frame you call 'bge.logic.getSceneList()' then blender will crash with a segmentation fault.

I have attached two zip files:

libFree1.zip

Extract the zip and open 'load.blend'
Hit P and blender will crash.
This is an example of the first crash.

libFree2.zip

Extract the zip and open 'load.blend'
Hit P and blender will crash.
This is an example of the second crash.

A temporary fix is to remove any added scenes before libFreeing, but this is often impracticable due to not knowing the name of added scenes.%%%

%%%The first crash is caused because LibLoad() assumes that any scenes it adds is merged with the current scene. Therefor, when the blendfile is freed, the scene information is just freed, but never actually removed from the scenes list. This is fine in most cases, but breaks if you actually have a running scene from the blendfile (like you do when you add an overlay scene).

I haven't yet investigated the second crash, but I get the feeling it's a similar problem.%%%

%%%Fixed problem 2 in r57626. I can not reproduce the first problem with the supplied blend file. It may have been fixed previously. Can you confirm that these bugs are resolved as of r57626?%%%
