Auto-focus of windows after "emtpy trash" action

[Rik]

Binary package hint: xorg

Let's say you have some windows open: 1 firefox, 1 Open Office, etc.
After "empty trash" action, where the mouse move the window got focus with a sort of auto-focus on mouse hover.
That can be stopped only clicking something.
So, if one don't take care of this, while writing down a password or something else, can ends written elsewhere because of an involuntary mouse movement.

Asked on italian Ubuntu Forum, I collect info from other users: This happen on 32 and 64 bit systems and with or without Compiz.
And has nothing to do with the Gnome window option auto-focus (that is not active).
