Package: bzr-loom
Version: 1.4.0~bzr95-1
Severity: important

The following sequence gets a branch that I would like to loomify:

=====
$ bzr init-repository --format rich-root-pack ~/Projects/bugs-everywhere/
$ cd ~/Projects/bugs-everywhere/
$ bzr checkout bzr+ssh://bzr.debian.org/bzr/collab-maint/bugs-everywhere/be.upstream/
$ bzr branch be.upstream/ be.devel/
=====

At this point the branch appears fine:

=====
$ cd be.devel/
$ bzr check .
Checking working tree at 'file:///home/bignose/Projects/bugs-everywhere/be.devel/'.
Checking repository at 'file:///home/bignose/Projects/bugs-everywhere/'.
checked repository <bzrlib.transport.local.LocalTransport url=file:///home/bignose/Projects/bugs-everywhere/> format <RepositoryFormatKnitPack4>
   373 revisions
   538 file-ids
  1113 unique file texts
 51952 repeated file texts
     0 unreferenced text versions
     4 inconsistent parents
Checking branch at 'file:///home/bignose/Projects/bugs-everywhere/be.devel/'.
checked branch file:///home/bignose/Projects/bugs-everywhere/be.devel/ format Branch format 6
=====

I set a branch nick, and it's still fine:

=====
$ bzr nick upstream
$ bzr info .
Repository tree (format: rich-root-pack)
Location:
  shared repository: /home/bignose/Projects/bugs-everywhere
  repository branch: .

Related branches:
  parent branch: /home/bignose/Projects/bugs-everywhere/be.upstream

$ bzr check .
Checking working tree at 'file:///home/bignose/Projects/bugs-everywhere/be.devel/'.
Checking repository at 'file:///home/bignose/Projects/bugs-everywhere/'.
checked repository <bzrlib.transport.local.LocalTransport url=file:///home/bignose/Projects/bugs-everywhere/> format <RepositoryFormatKnitPack4>
   373 revisions
   538 file-ids
  1113 unique file texts
 51952 repeated file texts
     0 unreferenced text versions
     4 inconsistent parents
Checking branch at 'file:///home/bignose/Projects/bugs-everywhere/be.devel/'.
checked branch file:///home/bignose/Projects/bugs-everywhere/be.devel/ format Branch format 6
=====

However, now I try to loomify the branch and it crashes:

=====
$ bzr loomify
bzr: ERROR: exceptions.TypeError: __init__() got an unexpected keyword argument 'ignore_fallbacks'

And any operation on the branch reveals that it's now corrupted:

Fortunately the repository remains okay:

$ bzr check .

But the branch needs to be deleted as unusable. It has been corrupted,
hence the ‘important’ severity level on this bug report.
