when branching from lp:~ubuntu-core-dev/upstart/ubuntu
branch from http works
getting a record stream of those texts (with the texts key stripped)
from the http side and pushing that into the writable mirror did not
error.

The problem persisted however, and branching with nosmart+ worked around
it.
