Blergh.

Thanks, I'll look in to what's going on there.

Hi,

This happens when you merge-package outside a shared repo. You can do
it inside one for now as a workaround. I've just committed a fix upstream.

Thanks,

James

This bug was fixed in the package bzr-builddeb - 2.3

---------------
bzr-builddeb (2.3) experimental; urgency=low

  [ James Westby ]
  * Some support for v3 source formats (Closes: #562991)
    - Those that look quite a lot like v1 are supported well.
    - .tar.bz2 tarballs are supported for import, building, merge-upstream,
      etc., but only enabled for the latter with a --v3 switch for now.
    - Multiple orig.tar.gz is not supported.
    - .tar.lzma is not supported awaiting pristine-tar support.
  * New "dh-make" command ("dh_make" alias) that allows you to start
    packaging, either in an empty branch, or based on an upstream branch.
  * Fix merge-package for native packages (LP: #476348)
  * debian/changelog merge hook to reduce the manual conflict resolution
    required there. Thanks to John Arbash Meinel and Andrew Bennetts
    (LP: #501754).
    - Requires newer bzr.
  * Fix merge-package outside a shared repo (LP: #493462)
  * Fix exporting of symlinks (LP: #364671)
  * Add --force option to merge-upstream which may help certain people.
  * Use system configobj if the bzr copy isn't available. Thanks Jelmer.
  * Make merging multiple-root branches work. Thanks Robert Collins.
  * Disentangle from bzrtools. Thanks Max Bowser.

  [ Jelmer Vernooij ]
  * Bump standards version to 3.8.4.
  * Fix formatting in doc-base.
