Subject: gnome-mount: wrong owner of device after switching user
Package: gnome-mount
Version: 0.7-2
Severity: important
*** Please type your report below this line ***
Dear Debian folks,
the desktop environment is GNOME. User1 uses the computer and is doing a
switch user (system → log out → switch user, System → Benutzername
abmelden → Benutzer wechseln), so that a second X session is started in
VT8(?) with GDM and gnome-screensaver is started for user1 (VT7).
User2 logs in and puts in a USB storage media. This device is mounted
and displayed, but is owned by user1.
When user2 logs in as the only user, everything works.
$ cat /var/log/syslog # user1.uid = 1000, user2.uid = 1002

In my opinion, somehow it should be detected, that gnome-screensaver is
running for user1 and that user2 is logged in and working on the system.
In this case, the owner of the device should be user2.
Thanks a lot and a have happy New Year everyone.
Paul
