Calling the panel settings does bring them up, so they haven't crashed. Looks more like compiz bug, will try to post in their bugzilla too. Reproducible: Always Steps to Reproduce: 1. start XFCE session 2. start compiz-fusion 3. try reaching for any panel
Looks like there are some well hidden options within compiz, which deal with screen edges/corners (e.g. Expo, Maximize, etc.) and these prevent mouse events from reaching xfce4-panel. Disabling all these options fixes the bug.
