This happens to me as well, most recently when switching from non composited to composited desktop using gnome-appearance-properties.

Workaround: `nohup gnome-panel &` -- gnome-panel keeps disappearing https://bugs.launchpad.net/bugs/446872 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
