Comment 6 for bug 222643

i confirm this behavior for mounting usb camera too.

when i switch to other users (after a session of mounting and unmounting of a usb camera)
 i see "left over" dialogs from the times when i plugged in the camera (on the previous user)
the camera is no longer connected (physically) . actually, they are confused...
when switching to their desktop and faced with those dialogs.

i think, pluggable mounted devices should display auto-mount-dialogs for the current user only.

maybe? another related issue/bug...
if i plug the camera on some user's session and then move to some other user's session
i get dbus error. and when i move back to the first user's session i see the auto-mount-dialog
still open on the desktop.
only when i move through all the open user's sessions on the system and close all the redundant dialogs
i can mount the camera successfully on the user's session.
