That's irrelevant.  It all has to do with how directory scanning is
implemented.

Of course our code was doing it.  That code is slated to be
potentially removed anyways after 0.24, so I'm not going to lose much
sleep over it.  Just don't put loops in your video filesystem that
gets scanned, or you are asking for issues.

Go ahead and call it a bug.  But the workaround for now is to not have
silly choices in your use of your filesystem. :)
