I suspect this is more of an issue with UDD than bzr itself, adding the UDD project.

Note that this only happens on natty, on oneiric, the merge-package command succeeds.

While merge-package on oneiric doesn't abort with a backtrace, the changelog merge results in an empty debian/changelog file:

  $ perl -e 'use Dpkg::Version ; print Dpkg::Version::version_check("2.0.37+cvs.JCW_PRE2_2037-1")'
  0version number contains illegal character `_'

seems relevant here but I'm not sure what we should do about that...
