PyQT, especially QApplication, segfaults when importing some other specific modules before instantiating QApplication().
This behavior occurred after the PR1.3 update.

Here's a proof of concept for this bug:
---------------------------------------------------
#!/usr/bin/env python
# -*- coding: utf-8 -*-
#

import sys
from PyQt4.QtGui import QApplication

##NOTE: Commenting this import prevents the segfault
##NOTE: Using the same import after initializing QApplication() works!
import gobject, glib, evolution

print "hello1"
app = QApplication(sys.argv)
print "hello2"

##NOTE: This does not cause a segfault:
import gobject, glib, evolution
print "hello3"
---------------------------------------------------

There might be other modules affected!
So far i found these three modules to trigger the bug (might be used i any combination, or each on it's own):
* gobject
* glib
* evolution

I can confirm the same bug.
Additional module that triggers this bug:
* location
