Pending Pay Later contribution with Separate Membership Contribution & Fixed Contribution Options gives New membership

See http://forum.civicrm.org/index.php/topic,19588.0.html :

Found a problem with membership contribution pages with Contribution Amounts section, Fixed Contribution Options, Separate Membership Payment and Pay Later.

When I use the contrib page to sign up for a membership using pay later and select "No Thanks" for fixed contrib, the membership contribution correctly has status "Pending (Pay Later)" but the membership has status New - should be Pending.

Found the problem on 3.3.5 and replicated on Demo on 3.4 r33809.
