unity-panel-service crashed with signal 5 in g_closure_invoke()

Binary package hint: indicator-appmenu

After clicking on ubuntu icon in top left corner the upper panel dissapeared and the system became unusable. I had to go to terminal tty1 and issue the command sudo pkill X...after that I got back to my session but this bug appeared.

This happened to me after restarting gdm in another TTY.

Looking at all the duplicates, this seems to happen only on login. The tiny backtrace in this bug (dups don't have any stacktraces(?)) suggests it's because indicator-appmenu can't connect to dbus and aborts (due to g_error). It's easy enough to make the appmenu not abort in that case, but that wouldn't be very useful. I'm looking into why it might have failed to connect.

See https://code.launchpad.net/~mterry/indicator-appmenu/dont-abort-at-drop-of-hat/+merge/48940 for a merge to deal with the crash aspect of this bug.
