duplicate applets in panel on login

[Gaël Roualland]

Binary package hint: gnome-panel

Hello,

Everytime I logout/login in the gnome environment the applets in the gnome panel are duplicated :
 - I have two instances of each one of them.
 - Trying to remove one of them, removes both instance of the same applet
 - After removing and readding the applet, they still are duplicated on session restart even with proper logout.

I have the following applets loaded in the top panel : System Monitor, CPU frequency monitor (two instances, one per core, and that's the only one for which I expect two instances), Notification area, Clock and Session Notification.

To reproduce :
- add a new applet
- logout
- login again
- the applet is loaded twice.

I'm running a dual screen system (:0.0 and :0.1). This happens only on my first screen (:0.0).
The system was upgraded from 10.04, but I was not using gnome before so I don't know if this was an issue on 10.04.

Thanks,

Screenshot before logout wth one instance fo applets only

Screenshot of panel after login, showing double applets.

In trying to take these shots I noticed this only happens when I remove the panels ont the second screen. So this is more a multi-screen/multi-panel issue.

Here's how to reproduce :
- login on a dual screen setup (:0.0 and :0.1) : four panels are loaded by default, 2 per screen with default applets.
- add applets in one panel (one instance of each) of first creen
- right click on panels on second screen, and "remove this panel", so no panel appear on second screen.
- logout
- login again
- panels are back on the second screen and applets are duplicated on panel on first screen.

I've read bug #439448, but to me it's not the same issue.. In my case, icons, are not wrong or missing, all applet zones are just duplicated, but hey are all functionnal : for instance on the provided screenshots, i can click on both clock applet to get the calendar, set volume on both spekaer icons and so forth...

I have only one instance of each applet process running though, but seems to me they are behaving just like they've been added twice on the panel.
Is there a way I can get some more traces to help ?

Thanks,
