I'm using KDE 3.1.2 from KDE built Debian Woody packages.

I thought it might be some bad interaction between a new version of 
libstdc++ and the HighColor plugin that was somehow exposed by PyQt, but 
I tried reverting back to a number of older libstdc++ packages up to a 
month old and it still exhibited the same behaviour.

The odd thing is that I first noticed this problem with my previous 
sip/PyQt 3.6 setup. So I thought I would try the latest snapshot to see 
if that would fix it. Since it hasn't, perhaps I should revert back to 
sip/PyQt 3.6 and try sorting out the problem from there.

I'm going to poke around the KDE source for the HighCOlor plugin to see 
if I can figure out what it's doing when it calls into libstdc++.

Thanks,
Gordon
