I am working on a PyQt 4 front-end for a python application that uses the GLib event loop itself. How should I fix it so that it works? Right now I get this Python GDB backtrace when I try to process something with the python core application after the GUI is loaded (and the Qt event loop is running)

Qt Code: 
  1. login.py, __init__
  2. login.py, show
  3. login.py, signin
  4. Signing in to account
  5. 65.54.239.210
  6. login.py, onConnecting: Connecting to server...
  7.  
  8. Program received signal SIGSEGV, Segmentation fault.

Do I have to use the GLib event loop in PyQt4? I'm lost.
Thanks. I hope someone can help me.
