The /Transfer/ in KGlobalAccel should be /TransferThis/, but that makes no 
difference in your example program, which as far as I can see is correct.

The backtrace shows calls to createPopupMenu just before the crash, and as far 
as I can tell from looking at the C++ code, that shouldn't be called. From 
Python's point of view, if you interrogate the KGlobalAccel object, or the 
KAccelAction object insert() returns, everything is set up correctly.

It could be a bug in the C++ KDE code, although I'd be surprised (a C++ test 
case would be helpful). It could also be some misunderstanding of how to use 
KGlobalAccel, but that seems unlikely too. It's probably a PyKDE problem, but 
it's one I'd find very difficult to track down and what time I have to spend 
on PyKDE is going to the upcoming KDE4 version. With that only a few months 
away, I'm reluctant to spend a lot of time on PyKDE3, and this looks like it 
would take a lot of time - I've spent a few hours on and off on it today

If I get some free time, I'll try to get back to it, but that's not likely at 
the moment - sorry. Anyone else is welcome to look into it.
