I've just upgraded to KDE 3.0.1 from KDE 2.2.2 and I'm now getting 
segfaults on most of the example scripts. Part of the backtrace is below 
(this is tut1.py). As you can see it is segfaulting in a KDE style plugin.

One example that still works fine is gears.py.

Has anybody else seen anything like this with 3.3rc1?
