[PyKDE] Segmentation fault when running PyQt app

[Gordon Tyler]

Hi all,

I seem to have somehow broken my PyQt snapshot. I'm using 
sip-x11-gpl-snapshot-20030322, PyQt-x11-gpl-snapshot-20030321, Python 2.2.2, 
and official KDE 3.1.1 and Qt 3.1.2-0woody1 Debian packages.

No matter how I recompile it, when I run a PyQt application, like the 
bigtable.py example from the example3 subdirectory, I get a segmentation 
fault.

This is the backtrace when run under gdb:

I noticed that it's calling into libstdc++.so.5 which is what python2.2 is 
linked to, but the Qt and KDE libraries are linked to 
libstdc++-libc6.2-2.so.3. Would that mismatch be causing this problem?

Thanks,
Gordon
