I tracked it down to the Space object. The crash appears in 
dSpaceDestroy() which is called in the __dealloc__() method. But I have 
absolutely no idea why it does so... it seems the space is already 
deallocated when the destructor is called, but why?

By the way, in the ODE manual I saw for the first time that spaces have 
a cleanup flag which is set by default and that this means they destroy 
the geoms contained in them. This could also lead to geoms being 
deallocated twice. So I called dSpaceSetCleanup(self.sid, 0) in the 
constructor of the Space, but this didn't change anything to our crash.

I also find it weird that it only happens in the unit test, I've found 
no other example that crashed....?
