pid file behavior
gajim complains on startup that another instance is running while we are just after a boot. the pid-file is not deleted when i logout from a gnome session (it is deleted when shutting down gajim with its menu entry).
also the pidfile does not contain a pid... strange, it's size zero here. so gajim has no chance to see if the pid is already there and a running gajim.
why isn't dbus (if avaiable) used to see if a running gajim can be found?
