I copied the format file from another working branch.  It has the
following contents:

    Bazaar-NG branch format 5

It's my home directory, so hopefully not.  :)

I only have branch, checkout and repository in the .bzr dir.  I tried
copying branch-format from a working branch and now get the following
error:

bzr: ERROR: No WorkingTree exists for
file:///C:/Documents%20and%20Settings/istevens/dev/ticker/trunk/.bzr/che
ckout/.

Here are the contents of the log:
