Yes, but it's more complicated in KDE because of 
queryClose/queryExit, and the fact that they're in 
kdeui/KMainWindow and KApplication is in kdecore. Interestingly, 
the code I used works when done in Python, but not when done in 
C++ (identical code in identical place) - probably the same kind 
of "destruction order" issues. It's also odd that closing from 
the title bar button has always worked - I tried emulating that 
sequence but it still segfaulted.

The fix really belongs in KMainWindow::closeEvent I think, and 
eventually I'll have to put it there (I believe Phil is 
abolishing the module .py files from sip), but it won't be 
pleasant to do.
