Oops. ;-) DBUS_G_CONNECTION_FROM_CONNECTION() should probably
special-case NULL to keep the value at NULL. This is really just a
debugging aid to catch any mixing between the G and non-G datatype.

Don't know offhand, but if you set the env variable for verbose output
(DBUS_VERBOSE=1 I think) for the _bus_ (not the client side) it will
probably have the answer in there somewhere.
