Hello Simon,

although DBusGLib-1.0.gir (and DBusGLib-1.0.typelib) has a reference 
to dbus_g_proxy_get_type() from libdbus-glib-1.so.2, the corresponding 
attribute 'shared-library' has yet been missing in the XML element 
'namespace'.  On the other hand in cairo-1.0.gir, the namespace element 
has this attribute.  That is why dh_girepository (together with 
dpkg-shlibdeps) is able to determine the dependency on libcairo-gobject2 
but not on libdbus-glib-1-2 for instance.  There is just the same issue 
with DBus-1.0.gir (and DBus-1.0.typelib) that has a reference to 
dbus_connection_get_type() from libglib-2.0.so.0.

Best regards,

Thomas Uhle
