Bug Description

gnome-panel fails to stop when a user logs out.

This results in a number of other problems. It's impossible to log in again without a big mess. An error will pop up: "I've detected a panel already running and will now exit." - This leads to a lack of any panel whatsoever.
I tried killing gnome-panel after logging out, and when it started again (when I logged in), most of the applets were unresponsive, and a couple of them, namely the ACPI battery monitoring applet (this is on a laptop) crashed or didn't start. This error has been reported from other people on other systems.

I now have to reboot to check session changes, apply new X configurations or anything like that. This could be considered a serious problem.

I am also seeing this problemhttp://ubuntuforums.org/archive/index.php/t-48217.html as well. Killing gnome-panel after logging out also doesn't seem to help for me as well; however, rebooting causes GNOME to load fine again.

Also, the problem seems to be intermittent. About half the time, I can log out and back in OK, the other half the time, re-logging back in results in the "I've detected a panel already running..." error message and a non-functional GNOME session.

Do you have a way to reproduce that bug? Do you have a custom ~/.gnome2/session? Do you have any gnome-panel running when back to gdm (you can use ctrl-alt-F1 to switch to a vt, log in and use ps ax | grep panel)

Changed in gnome-panel:

I have this too - seb128, I don't know what you mean by a 'custom ~/.gnome2/session' I just have one that was generated by the save session feature of gnome 2.12.

I get it about 50% of the time if I logout of GNOME, then log back in immediately, in this situation, there is a gnome-panel running (it never quit when I logged out of my first login). In fact when it does happen I have lots of processes left over from the previous login - bonobo-activation-server, gnome-panel, gnome-vfs-daemon, mixer_applet2 and esd.
