Yesterday I've been debugging for few hours my regexp in Converter class
which seems to be not working correctly, when the real problem was my
Converter's to_python() method which doesn't handle ValueError.
Django instead letting me know where lies the problem simply didn't find
matching pattern and return 404 (so it acted like a regexp problem).
The line responsible for that is:
https://github.com/django/django/blob/26d16c07fdc4a297daca554afa6375c70d6d82a9/django/urls/resolvers.py#L256
I think this should be handled in different manner. At least some note in
the documentation letting user know that all ValueError's in Converters
method are handled silently (which is somehow not intuitive).
