Cool!

A couple of alternatives occurred to me.

First, there's an os.walk function which you could use like this, also
switching the filelist to a value returned from walk_tree.

...
def walk_tree(d):
    result = []
    for root, dirs, files in os.walk(d):
        result.extend([os.path.join(root, f) for f in files])
    return result
...
filelist = walk_tree(options.folder)
...


Also the itertools.cycle function can simplify the switching code
thusly:

	...
        self.filelist = cycle(filelist)
        # self.filelistlen = len(self.filelist)

    def change_background(self):
        """
        Change the gconf background key to the next image file in the list.
        """
        self.ready.acquire ()
        self.client.set_string('/desktop/gnome/background/picture_filename',
                               self.filelist.next())
        self.ready.release()
        return 1 

By the way, is the thread.Threading.Condition lock (acquire/release)
necessary?
