Good to know. Introspection isn't to punish :-)

OK. But maybe you add also one or two tests to check this error functionality.

Sure, this can wait.

Btw, I have just pushed a larger patch to master. It implements a first
shot on the org.freedesktop.DBus.Monitoring.BecomeMonitor
functionality. If you want to see how it works, just call
(dbus-register-monitor :session) . There will be a new buffer *D-Bus
Monitor*, which shows you D-Bus messages similar to what the UNIX
command "dbus-monitor --session" does. The point is that you can
register your own handler to the monitor; if you don't declare an own
handler, the default handler `dbus-monitor-handler' is taken.

As said, it is just a first shot. Proper documentation is missing, and
not all arguments of `dbus-register-monitor' seem to work as
expected. But you might see which direction it will go; any feedback is
appreciated.
