Comment (by SergeyBiryukov):

 Looks like I used [attachment:22801.diff] instead of
 [attachment:22801.2.diff].

 [attachment:22801.4.diff] is a partial refresh of
 [attachment:22801.2.diff] and [attachment:22801.3.diff], and is my take on
 further clarifying the error handling.

 * A numeric `$term` is allowed, as long as it's not empty.
 * A non-unique slug is also allowed (it will be regenerated), as long as
 the name is different.
