Kleopatra Name field constraint on 2 names

When creating a new certificate with kleopatra the "enter details" window in the Certificate Creation Wizard Requires you to enter a name.

1) if you type in one name, kleopatra says "Name is incomplete" expecting 2 names
2) If you type two names
ie "Firstname Last"
3) Enter in an email
ie "<email address hidden>"
4) go back to the "Name" field and delete one of the names... it accepts that name.

This is inconsistent behaviour. If two names is absolutely required by PGP/gnupg itself or something...then it shouldn't let you go "Next" after you've removed one of the two names. If, however it *isn't* required, then it is an artificial constraint on what names you can type in (which could potentially snag people like Madonna who have one name, or people who prefer to have a key assigned to their pseudonym, say).
