Why a question can exist with no tags?

For example https://math.stackexchange.com/posts/613902/revisions.

    $\begingroup$ Looks like this is a bug with suggested edits, there's another instance of this on a different site: gaming.stackexchange.com/posts/147067/revisions $\endgroup$

  • $\begingroup$ I concur, this is a bug. $\endgroup$ Dec 20, 2013 at 15:48
  • $\begingroup$ Although I don't think it happened in this case, something similar can happen when a question is migrated to M.SE and none of the tags exist as tags here, although I think it actually gives the question the tag (no-tags). $\endgroup$

    $\begingroup$ @Daniel I thought it was untagged. $\endgroup$

  • $\begingroup$ @ColeJohnson That's likely. I just recalled from (a rather poor) memory. $\endgroup$

  • $\begingroup$ Either way, this is a duplicate of a MSO post. $\endgroup$

  • $\begingroup$ @Cole Johnson: Thanks for telling us that untagged question will fall into the untagged "tag". $\endgroup$ Dec 21, 2013 at 7:02
  • $\begingroup$ @ColeJohnson, can you link to the MSO post, perhaps by editing it into the top of the question? $\endgroup$

Thanks for the report.

We did a major tag change on Dec. 20th, this introduced this bug and was fixed an hour later on the same day.
