Comment 4 for bug 394529

This is happening to me multiple times a day.

One method to replicate the bug (although it happens in a lot of other situations):

Requirements
===========
- Have Compiz enabled
- Have gnome-do set to the Docky theme

1. Press Ctrl+Space to bring up Do and type "switch" and select Compiz-switch to disable compiz
2. Repeat step 1 to re-enable compiz
3. Move your mouse so that Docky appears and click on an icon to start it.
4. Watch as nothing happens and see how gnome-do is no longer running. Logging the errors will reveal the exception that is not being handled.
