This is fixed in r1668 and will be available in 1.6. I added a
comment to the ticket, but it's worth noting here as well.
You should make sure you that you have all properties and states set
appropriately before invoking any callbacks on init. By invoking a
callback, you're opening yourself up for a user to access any and all
parts of your widget API, not just one or two methods. This shouldn't
be a problem if you invoke the callback at or near the bottom of your
init method.
