 Replying to [comment:74 mikemeinz]:
 > I temporarily added an **error_log($requested_url)** call to
 canonical.php to see if I could determine the cause.

 populated correctly and if not exit the function.

 If you go back to post #10 from 8 years ago, I had found the same (in my
 case the URL was "/" - so no host) and I circumvented it similar to your
 suggestion.

 It's a trivial fix to a very obvious problem - yet after 8 years, it still
 fills people's logs.
