I've also encountered this problem. I've tried all advices from this page, and nothing helped. As if this problem is locale-specific, I've tried this:
$ LC_ALL=C lxpanel &
** (lxpanel:7100): WARNING **: Group count mismatch, ctrls = 2, groups = 2, symbols = 4
$ LC_ALL=C lxpanelctl run $ lxpanelctl restart $ lxpanelctl config $ lxpanelctl menu
Nothing happens.
However, Run menu item works.
