The problem isn't in the admin. For example, GenericIPAddress.objects.filter(ip=' ') also crashes (using the model in tests/model_fields/

I was't this much specific in the Summary as not only space causes the DataError, but apparently a syntactically wrong IPv4/IPv6 address, any of 'string', '', 'fffg::'.

I selected admin component as I considered the DataError from ORM as part of correct "user interface" to the developer. What is clearly wrong IMHO is 500 from using the admin.

A possible solution would be to validate the value in DatabaseOperations.adapt_ipaddressfield_value. Possibly trying first with our own validator, then round-tripping to the database as last resort. Maybe a ValidationError before running the query may be catched easier than the error coming from the database.
