Comment 1 for bug 670284

I'm going to tentatively reassign this to qbzr, as I think the cause may be there rather than bzr itself: it appears that qbzr is specifying a revision ID to 'bzr update' that isn't in the ancestry of the branch, which causes this error. Perhaps it is trying to update a working tree of the test_feature branch to a revision only found in the ancestry of the trunk branch?

I'm not certain the root cause isn't bzr itself, so please feel free to assign it back if you think I'm wrong.
