I can confirm the bug and it should be fixed in master.

What happend was that Org grabbed the document title from the headline
(good) and tags:t told Org to include the tags (Okay), but then Org
forgot to check if there are actually tags in the headline when
creating the document title with a `format' w/ a placeholder for the
tags.

Best,
