I've read the thread started by Caleb and I am having the same seg
fault as him. I'm trying to get to a point where I can use Stackless
and PyQt on both Windows and Linux so I'd like to see if there's a
solution to this problem as well. I'm using Python 2.5 Stackless 3.1b3
with Qt 4.2.3 and PyQt 4.1.1. This is the stack trace I get after I try
to import QtCore:<br><br>(gdb) run<br>Starting program: /usr/bin/spython<br>[Thread debugging using libthread_db enabled]<br>[New Thread -1210063184 (LWP 16805)]
