I've seen this happen a few times. The developer has their latest version approved for the public for the first time, and then deletes this version for whatever reason. This puts the add-on in an incorrect state: all versions In Sandbox (or no versions at all) and the add-on status is Public. The end result is that the add-on page becomes inaccessible. When deleting an add-on version, there should be a check to make sure that the add-on status is still correct. It should change it to In Sandbox if there are no Public versions, and to Incomplete if there are no more versions. There should also be a big warning message to developers for both cases.
This is a PHP bug. Verifying it doesn't do the same thing on the new versions page is good enough to mark fixed.
The status doesn't change when versions get deleted, so I'll add this in. Chatted to jorgev and In Sandbox is STATUS_UNREVIEWED and Incomplete is STATUS_NULL.
