Disabling MPROTECT in Python ( sudo paxctl -m /usr/bin/python2.7 ) solves the issue but that defeates the purpose of a hardened system.

Reproducible: Always

Steps to Reproduce:
1. Use a hardened profile and kernel with Pax
2. Run gwibber
3. Watch it crash
Actual Results:
PAX kills the process

Expected Results:
Gwibber should run
