It should work anywhere that supports gmodule.

there really should be a glade_xml_signal_autoconnect_with_data
since g_signal_connect expects a user_data parameter it doesn't make 
sense to have
the more limited glade_xml_signal_autoconnect.  when it could easily be 
implemented
with a call to glade_xml_signal_autoconnect_with_data( glade, NULL );

I agree.
