My suggested solution does not fully work for me either... I experience same phenomen like all others: After logging in (or after killing lxpanel and re-starting "lxpanel -p Lubuntu" from terminal), I can call "lxpanelctl run" exactly once. Any further call finishes without response.
The bug appears with default profile, too. I.e. it doesn't matter if I call "lxpanel" or if I call "lxpanel -p Lubuntu".
