Comment 4 for bug 742045

OK - it probably was the launcher which I did eventually find in ~/.local/share/applications when doing a backup of that folder. I guess that's what fixed it, not the latest upgrade or removal of gnome-panel.

You can close this bug, I guess, but most people won't know to look in ~/.local/share/applications for a desktop file to delete. That should be done automatically when removing the application. I also deleted a lot of other launchers from stuff I had removed. Could be those launchers are ones I created or that had something to do with the old menu system. I don't know, but they need to be automatically cleaned up somehow since you wouldn't expect the average user to even realize there is a .local directory in the first place.
