This looks like the (unintended?) result of 80e145fc9.  CC'ing Paul
who made that change.

(FWIW, I'm not sure why this is a problem.)

P.S. Please don't change the Subject when you post to a bug, keep the
original Subject you used when reporting it.  That makes looking for
related messages in a mailer easier, at least for me.
