Affects: gnome-screensaver (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I lock the screen, gnome-screensaver starts and I choose to switch user.
Gnome-screensaver displays a list of users. I select one user and ask to
switch, GDM starts and ask me again witch user I want to login, GDM
should only asks for the password of the user selected in gnome-
screensaver's list.

After login with another user, I connect my USB-key which is
automatically mounted with the uid of the other user who has locked his
screen, so I can't unmount the USB-key ! This bug doesn't appear
everytimes, I think that both sessions have a gnome-volume-manager
running and the first process that get the focus mount the USB-key for
his user.
