Remmina remote desktop window not visible when using ALT-TAB

Binary package hint: unity

When connected to a remote desktop using remmina, you can use full screen mode. There's a menu on top of the full screen window when the mouse hover over there. There's a minimize option and it works, remmina's remote session windows goes to the dock, but in that state ALT-TAB does not show remmina's minimized windows as a option to switch.

Steps to reproduce:

1) Open remmina
2) Connect to a remote desktop
3) Activate full screen mode
4) Move mouse over the top center of the screen and press minimize
5) ALT-TAB to go back to the minimized window (you can't)

If the windows is not in full screen, the bug does not appear. I guess the full screen mode fools unity or compiz.
