Comment 14 for bug 540950

I tried your version just now, and I get the same error.
However: If I remove the line:
self.applet.setup_menu(self.pp_menu_xml, self.pp_menu_verbs,None)
dockbarx loads! hooray! pity about the lack of the menu.
However, I had some changes from
So I went on to defer the menu loading instead of removing it, with gobject.idle_add, but that caused the error too.
So I tried gobject.timeout_add with 20000. That did not work either. I don't know why this is.
No matter what I do, that line causes the error.
