if anonymous when he/she try to register forgot to select avatar from avatar selection (if it is required)
there is info about it inserted into watchdog as error.
IMHO it is really uselessly - If any robot or visitor try to submit register form without avatars, you got new error into watchdog.
If you really think that it make sense to have info about it in watchdog, could you please add option into admin zone for admin when he/she can select if he/she want to insert this info into watchog?.
