    libtracker-miner,miner-fs,extract: Don't assume g_dbus_info_new_for_xml() never fails
    
    Not a big deal because the introspection XML is hardcoded and thus shouldn't
    break g_dbus_info_new_for_xml(), but anyway, better get an error message than
    a segfault if the xml is ever broken...
