Comment 4 for bug 759174

This Python script demonstrates the problem. Run it like this (also added to bug description):

1) Download and run script from gnome-terminal (important).

2) When script is running, right-click gnome-terminal icon in Unity launcher.

Unity crashes. With the fix in branch, Unity doesn't crash and displays just "Item 1" in the dynamic part of the quicklist, which is the intended behavior in the case of this script.
