The error is on C-level. AFAIK it occurs when a Python-C-function 
returns "NULL" without setting an exception.

It's hard to say where it really occurs. I'd use a debug-build of PyQt, 
and possibly Python, and then investigate using gdb.

Alternatively, what happens when you do some "dummy"-work that doesn't 
use signals and no other libraries?
