branch fails with "bzr: ERROR: The branch ... has no revision None."

[Tim Penhey]

I have a brisbane-core branch of launchpad which I wanted to branch into a fresh repository.
The branch command fails.

$ bzr init-repo --no-trees --development-rich-root lp-bbc

  shared repository: lp-bbc
$ cd lp-bbc
$ time bzr branch ../lp-bbc-pre-reconciled/devel/

This may be a dupe. Please try
'bzr push /tmp/newpath'

$ bzr push /tmp/other-path
bzr: ERROR: Revision {('Arch-1:<email address hidden>%launchpad--devel--0--patch-154',)} not present in "<bzrlib.groupcompress.GroupCompressVersionedFiles object at 0x9df7bac>".

A ghost perhaps?

Could this be related to the 2485 revisions missing parents in ancestry after `bzr reconcile`?
