[PyKDE] seg fault on different 'from qt import <x>'

[Patrick Stinson]

In using my own C++ library, I get seg faults when my main script does

from qt import QApplication

instead of 

from qt import *

INFO:
I am writing a qt-ish syntaxed audio library in C++ using sip and am using WAD 
for stack traces. I noticed that some of my code runs a bit slower (judging 
by some stdout output) when I use the second method above. This execution lag 
could very well be preventing a thread-related bug in my code from surfacing. 
The results are very consistent\ regarding seg-faults and import methods.

I'm failry sure that my code has thread-related bugs, but I'm looking for 
comments as to why the import code would cause the error, how 'import' works 
in this case, etc.

------------------------------------------------------------

stack trace info:
'pkaudio: ... ' is my C++ code
'[38542 refs]' is python spitting debugging output after deleting something
' ... _ZN2PK... ' are my C++ destructors and misc methods.

the stack trace always looks the same with this problem, and the seg fault is 
always reproduced by importing only QApplication from qt.

cheers!
