Privacy problem: on resume Unity bar visible through GDM

[Martin Eve]

Binary package hint: unity

On resume from standby mode and upon reconnection to a wireless network, the Unity global bar becomes visible behind GDM's password dialogue, thereby revealing certain user-specific confidential details. This includes the name of the wireless network, the current focused application name (including window title, which could be a sensitive web page). In addition, the currently focused application was visible for a good second on my last resume, which could certainly include confidential information.

Expected behavior: all user-specifics should remain hidden behind the GDM prompt.

The bug is present also in oneiric 64bit!

And in precise.

I have this bug in 12.04 when I go back from a locked session.

Why do we still use this dialog box when we could systematically use the gdm greeter whenever we quit/lock/switch users ?
