Not really. The C documentation
(http://library.gnome.org/devel/rhythmbox/unstable/ch04.html) is
incomplete but it might help a bit for the parts that translate
directly to python.

The available properties are defined in rhythmdb.h:
http://git.gnome.org/browse/rhythmbox/tree/rhythmdb/rhythmdb.h#n150
When accessing these in python, you remove the 'RHYTHMDB_' prefix,
since they're already in the 'rhythmdb' module.
Alternatively, run 'filter(lambda x: x.startswith("PROP_"),
dir(rhythmdb))' in the python console.
