A rather horrible approach would be to set a timeout in the activate()
function for long enough that rhythmbox is *likely* to be ready... You'd
have to catch an exception in the case that it wasn't ready (and
presumably continue the timer instead of stopping it).

If that's the approach you want to take, look at the gobject.timeout_add
function. It's called like:

gobject.timeout_add(6 * 60 * 60 * 1000, self.__update_catalogue)

with the first argument being the number of milliseconds to wait, and
the second being the function to call. If the function returns False
then the timeout is discarded. If it returns anything else, then the
timeout function is called again in another n milliseconds.

Like I said, it's probably not a very "clean" way to do it, but it would
likely work.
