Comment 9 for bug 537885

The problem is happening in GTG/tools/openurl.py where it forks a process to check if xdg-open or exo-open are available on the system.

If I make the following change, the crash is prevented (but we lose the ability to detect these programs - so only works on a gnome desktop):

I don't know how to fix it (don't have time to experiment further) but this seems to be where the problem lies.
