Description of problem:

gnome-panel seems to hang on logout. If I logout, just the background remains
for 10-20 seconds and then the rest of the logout finishes and gdm is back. If I
then go to a console, I can see that gnome-panel is still running and a few
other things too. I then can't log in again because a new gnome-panel detects a
previously running one.

Version-Release number of selected component (if applicable):

gnome-panel-2.13.91-3, gnome-applets-2.13.4-3

How reproducible:
Everytime I log out.

Steps to Reproduce:
1. login
2. logout
3.
  
Actual results:

logout eventually occurs but gnome-panel is stuck preventing logging back in
properly.

Expected results:

gnome-panel dies when gnome-session dies.

Additional info:

I'll include some back traces but they look useless to me.
