In sip/kparts/event.sip, comment out the ConvertToSubClassCode block as shown 
below and recompile kparts (python configure.py -lkparts && make && su 
-c"make install"). Works for me.

khtml (and the new kmdi module) would have the same problem because they both 
depend on kparts. The only thing this change affects is "typecasting" of 
KParts::Event subclasses - for example if a factory function creates a 
KParts::GUIActivate even but returns KParts::Event, there is no way in Python 
to "up-cast" to the subclass type (except via the commented out block).

I expect the "sipClass=NULL" stmt is causing the problem, but I'll have to 
look into what to replace it with. I don't expect commenting this stuff out 
will affect many people (if anybody), so I probably won't give it a high 
priority unless someone has a problem with it. 

I'll probably issue a patched tarball sometime around the time I release the 
KDE 3.3.beta1 snapshot, which will be a week or two.

Thanks for re-activating this bug - it fell through the cracks. Let me know if 
the problem persists.
