[pygtk] signal emission problem with pygtk-2.11

[Mystilleef]

Hello,

PyGTK version 2.11 crashes my application whenever its "close-document"
custom signal is emitted. The signal is emitted to alert objects
connected to it to perform necessary cleanups before the application
exits. This problem only occurs with version 2.11. Versions prior to
2.11 allow the signal to propagate without problems. I welcome any help.
Let me know if you need more information.

Thanks
