For found the issue for the Gnome Shell and will thus switch back to Qt4 for now. The problem for the not reappearing window will also be fixed with the next issue.
As for Unity, I don't have a clue...
The only thing I could do right now is to add an option to remove the icon for good and to dissable hiding the window (only minimizing would be available). But for this I would need some user feedback. Do you think this would be a good option?
