Thanks for your bug. What version of Ubuntu do you use? Could you install gnome-panel-dbg and get a backtrace of the freeze with it?
When the panel is frozen:
- gdb -p $(pidof gnome-panel)
(gdb) thread apply all bt
When that happens is the menu still working? Could you try killing applets and notice if stopping one of them unfreeze the panel?
