When a script that used setAttr for Camera Data objs (the bug also
affected some other modules) was executed multiple times, Blender
would crash after, let's say, the first 5 or 6 tries. Problem, as
Guignot pointed, was with reference counting. Should be ok now, all
affected modules were fixed.
* The Scene module is now "complete" (= 2.25).
* Made some necessary updates to Object and NMesh.
