LinuxQuestions.org - Maemo PyQt4+Gstreamer Segfault (Python)

I'm having a strange problem on my Nokia N900, running Maemo. The code I'm running is:

Code:

#!/usr/bin/python



import sys

from PyQt4 import QtGui



import gst                          # ***

app = QtGui.QApplication(sys.argv)  # ***

When I run this, it prints "Segmentation Fault". However, if I comment out either of the two lines I marked, then it doesn't complain and terminates normally.

The fact I get a segmentation fault rather than a traceback implies to me that it's importing one or both of the libraries in compiled C/C++ form, which is then throwing the error. This means I have less of a meaningful traceback. Is there a way to use gdb (or another programme) to debug a module which I'm importing into python? Can anyone shed any light on this? This problem doesn't exist on my desktop - so I'm guessing it's something to do with the Maemo configuration (hence posting here and not in programming ;))
