Comment 2 for bug 315899

photoalbums_screen has not defined it's is_interested_in_play_action method. If this method was defined so that it would return False when there are no photos, then this exception should go away. The exception is mostly harmless, but I think it might cause the odd behavior of being able to play a paused music or video if you were on the photo albums screen, and that would be a pretty weird.
