I know you're warned not to do this, but you're also told to assign an avatar to the anon user in the template picker for photos...

Modifying the anonymous user by adding a template causes an exception that isn't logged as far as I can see. If you're really not supposed to change anything for the anon user, perhaps it could be locked or at least, the notes for the photo templates need updating and the error message could use being a bit more polite than throwing an exception like this ;-)

I think the reason is obvious from the error.

You can't suppose an Anonymous user as a normal user.  As you can't provide an email or many other field for a user you can't assign an avater to it or do several other operations on it.

I wouldn't argue with you if you say that you're not supposed to do that. However, as I said in my original post

If you're really not supposed to change anything for the anon user, perhaps it could be locked or at least, the notes for the photo templates need updating and the error message could use being a bit more polite than throwing an exception like this ;-)

I don't really mind if people can edit the user or not, but if you can't then this isn't the best way of handling it.
