Revision not present error pulling from knit to rich-pack-root repository

16:46 <siretart> hi folks
16:47 <siretart> can someone look what going wrong here:
                 http://paste.ubuntu-nl.org/62805/? is this a known bug, or did I manage
                 to fuck up my branch on launchpad?

>> bzr get http://code.launchpad.net/~siretart/aspectc++/debian
http://code.launchpad.net/%7Esiretart/aspectc%2B%2B/debian/ is redirected to https://code.launchpad.net/~siretart/aspectc++/debian/

The source branch is a knit format 1 branch; maybe reconciling and upgrading it would fix it?
