I'm not sure if this is a bug or I should handle it. :)

What steps will reproduce the problem?

Create users collection in mongodb. Login as user. Make auth key no more valid and /yii/web/user will try do this but id is not a string but ObjectId and it will throw Array to string conversion

Yii::warning("Invalid auth key attempted for user '$id': $authKey", METHOD);

What is the expected result?

Maybe do (string) $id ? I'm not sure

What do you get instead?

Array to string conversion exception

@cebe that doesn't seem to be debug issue but core one.
