ERROR:dbus.connection:Exception in handler for D-Bus signal:

[Zaos]

Pidgin 2.4.1
Screenlet 0.3.3

Well, my dbus seems to work anywhere else and that's not "critic" since the applet seems to work too...
But this message appear in tilda (a terminal like) when i launch (juste before the applet load, so after pidgin had loaded) or close pidgin ((launching from menu))

ERROR:dbus.connection:Exception in handler for D-Bus signal:

Strange things is that if i launch from gnome-terminal instead from menu, a different error appear (not linked with the applet this one i think)

libnm_glib_nm_state_cb: dbus returned an error.
