Description: libxul.so segfaults when application tries to use GtkMozEmbed

Additional info:

glib2 2.22.4-1
xulrunner 1.9.2—2
firefox 3.6-2

Steps to reproduce:

Here is a test application in Python, although I tried C and PHP, and all of these segfaults as well.
Create a text file called test.py and put the following code in it:

#!/usr/bin/python
import gtk
import gtkmozembed
win = gtk.Window()
browser = gtkmozembed.MozEmbed()
win.add(browser)
win.show_all()
gtk.main()

Make the file executable by issuing

chmod +x test.py

Execute the file and you would get 'Segmentation fault' at the console and something like

test.py[1589]: segfault at 0 ip b56c87ab sp bf80f198 error 4 in libxul.so[b552b000+bd0000]

at the bottom of dmesg output.

Temporary fix:

This problem may be fixed by issuing

export MOZILLA_FIVE_HOME=`grep moz_libdir= /usr/bin/xulrunner | cut -d= -f 2`

before executing test.py, but that's no good, and there should be another way to fix it correct.
