bzrlib.errors.MalformedTransform on bzr shelve command

[Alexander Taler]

When attempting to do a bzr shelve, I get the error shown below.

Here's the status:

 added:

   appl/core/lib/python/deliver/__init__.py

   appl/web/lib/python/deliver/web/settings.py.orig

Here's the command:

    bzr shelve --all -m 'version template tag take 2'

The changes get put on a new shelf, but they are left in the working tree, and the following error messages are printed:

When I subsequently do a revert to get rid of the changes, I get the following error messages about conflicts, perhaps this is the origin of the shelf error:
