Comment 13 for bug 718926

Okay, so I've now got a log from unity-panel-service. I think this is the relevant part. I had a terminal open and that wasn't causing a problem. Once I was just switching between Firefox and the desktop it happened more readily. I believe that "96469227" is Firefox (which lost its menus) and "98610656" is my terminal.
