unity-panel-service crashed with SIGSEGV in gtk_menu_tracker_remove_items()

[Reiner Jung]

The crash report showed up after working on the new installation of eclipse luna. I had already created a workspace and added projects to the new workspace. The menu of Eclipse was showing. Then I started a Run Configuration in Eclipse containing the imported projects. It took some time, but the started Eclipse+My Projects showed up. The central menu was not working. However, that might have had a different cause. Nevertheless, the crash report showed up. So this might have to do with running Eclipse or it might have other causes. For example, I have four Eclipse instance running at the moment. On a 2 GB netbook + 2 GB swap, this might have had some effect on some services where unity-panel-service depends on.

I did not see any problems during my excerise, like missing menus or blinking/dissapearing and reappearing apps. However, I was kinda distracted looking at Eclipse logs and messages. So I might have missed it.
