DBusException
Jul 1 2007, 9:37 AM EDT | Post edited: Jul 1 2007, 9:37 AM EDT
I'm not too good with python, but I managed to detect that the script was throwing a DBusException each loop iteration. Here's the traceback...

Traceback (most recent call last):
File "./awn_plugin_listen.py", line 41, in main
vars = {'title' : listen.get_title(), 'artist' : listen.get_artist(), 'album' : listen.get_album()}
File "/var/lib/python-support/python2.5/dbus/proxies.py", line 85, in __call__
return self._proxy_method(*args, **keywords)
File "/var/lib/python-support/python2.5/dbus/proxies.py", line 169, in __call__
reply_message = self._connection.send_message_with_reply_and_block(message, timeout)
DBusException: org.freedesktop.DBus.Python.dbus.exceptions.UnknownMethodException: Traceback (most recent call last):
File "/var/lib/python-support/python2.5/dbus/service.py", line 429, in _message_cb
(candidate_method, parent_method) = _method_lookup(self, method_name, interface_name)
File "/var/lib/python-support/python2.5/dbus/service.py", line 222, in _method_lookup
raise UnknownMethodException('%s is not a valid method of interface %s' % (method_name, dbus_interface))
UnknownMethodException: Unknown method: get_title is not a valid method of interface org.gnome.Listen

Have I done something wrong setting this up?

PS, without additional handling this just looks like its working but doing nothing. Do you find this valuable?

With further mucking around, it looks like I can get the method current_playing ( http://www.listen-project.org/browser/trunk/src/dbus_manager.py#L137 ) but not get_title or artist. Why might that be I wonder... Do you find this valuable?

Using DBUS Inspector I find that the methods available on Listen 0.5 are: quit,play,current_playing,play_pause,next,enqueue,hello. previous. Without get_cover_path, current_position and current_song_length there's not much point in an AWN hook.

So, have I done something wrong to miss out on these extra DBus methods? Do you find this valuable?
