That's the database's fault, not the API's. If this causes trouble,
someone should write a maintenance script to delete these ghost pages.

The same is true for the UI: if you go to
Special:Whatlinkshere/Slashdot, you'll see that [[/.]] is listed (and
linked), but clicking the link turns up an error message.

That's because generators are based on page IDs: list=backlinks passes a
list of page IDs to prop=revisions internally.
