First of all, I'm assuming the remote peer is a message bus? Either
way, please don't use the mailing list for reporting bugs - please
file a bug at http://bugzilla.gnome.org against the gdbus component.
Also, please try attach the output when running the program with
G_DBUS_DEBUG=all cf.

 http://developer.gnome.org/gio/unstable/ch03.html

Note that you can use gdbus(1) for this like this

 DBUS_SESSION_BUS_ADDRESS="tcp:host=localhost,port=8080,family=ipv4" \
 gdbus introspect --session --dest org.freedesktop.DBus --object-path /

instead of writing a C program. Might be easier when testing connectivity...

HTH,
