Is there a way how can I help you (probably the question marks -
source is from another module ) or something else ?

I'm afraid that doesn't help me, either, as you can see there's no 
debugging information in there (the "??" question marks should be 
function calls actually).


Apparently there's a NULL pointer deref somewhere, I'll try to track it 
down on my own.
