AAAAAH. Ok. I found it. It turned out to be a prematurely freed object 
instance which must have garbled the pointer.

I could bite my head off right now. Be assured that I'll be back over 
the next few days with some questions regarding that - as the Irrlicht 
engine employs it's own reference counting scheme which I'd love to 
integrate with Pythons - if somehow possible, that is. Which needs some 
research.

I know why I prefer languages with GC over the 
allocation/deallocation-madness of C++...

Thanks a ton for the great help, without the overloading-issues solved I 
would have never come so far!

Regards,

Diez
