Testing
-------

On Stock Ubuntu (14.04 used):
1. Create Project.
2. Create folder in project.
3. Right Click folder.
4. Select 'Open'.

Before: Resulted in Segfault prior to fix due to a null pointer dereference.
After Fix: Pops up a dialog alerting the user that there is no compatible file manager.


Thanks,

Matthew Suozzo
