Recipes: failed to build after altering series branch

Looks like the recipe system isn't picking up changes quite corrrectly.

With this recipe: https://code.launchpad.net/~brightbox/+recipe/ruby-stomp-edge

Changed the target of the series lp:ruby-stomp from lp:~brightbox/ruby-stomp/trunk to lp:~brightbox/ruby-stomp/github-trunk
edited the recipe to point at the new branch (which then immediately replaced the entry with lp:ruby-stomp as expected).

Then renamed the old branch from lp:~brightbox/ruby-stomp/trunk to lp:~brightbox/ruby-stomp/gitorious-trunk

The auto-build then produced the following error: (http://launchpadlibrarian.net/62247046/buildlog.txt.gz)
