I had a branch giving the "Revision {set([('null:',)])} not present ..." error with bzr 1.9-1~bazaar1~intrepid1. It is a "1.6" format branch, if that helps.
I just tried using bzr.dev with your patch applied, and successfully pushed to the branch. It looks like Launchpad successfully scanned the change I pushed, so it looks like it worked.
