I'm not sure what you expect to happen when validating a non-existent resource with a badly formed validate parameter.

The problem here is that kind is None, and so doesn't have an endswith object. kind can be supplied in a number of ways (through src, definition and kind itself) so it's difficult to check every single edge case (not saying we shouldn't). While we could improve error handling, this failure is not at all surprising
