'Minimize' action in system tray does not minimize the Quassel to the system tray
The minimize action in the system tray does not minimize the application to the system tray, in fact, the action does nothing.
The restore functionality works just like expected.
This behavior is confirmed by IRC user Markb, who is using 0.10.
I am using v0.11.0 (dist-5199111) myself.
