At risk of talking to myself... on a related note, if you request a
garbage name, the method returns 0 but does not set an error, because
the library uses:
_dbus_return_val_if_fail (_dbus_check_is_valid_bus_name (name), 0);
At the start of the function, amongst others.
This and others like it should either be made to return an error, or the
fact this function can return 0 in unspecific error cases (rather one of
the return values in the documentation) made clear in the API
documentation and spec.
