The problem is that, at least with xubuntu (xfce indicator plugin), the messaging menu never appears in the panel, unless libmessaging-menu0 gets installed, although applications using it are installed (e.g. thunderbird). But of course this can also be resolved be letting thunderbird recommend (or suggests) libmessaging-menu0.
