29782	Better error message when filtering users with AnonymousUser	Sveder	Ramon Saraiva	"When trying to filter a model with User ForeignKey on AnonymousUser, we get a cryptic:
`Exception Value: int() argument must be a string or a number, not 'AnonymousUser'`

For example:
https://stackoverflow.com/questions/3439709/how-to-cater-for-anonymoususer-when-filtering-based-on-user

I think this deserves a better error message, for example something like:
`ValueError(""Can't filter User field with AnonymousUser"")`.
