Cannot use backslash character in file name

[James Ascroft-Leigh]

I am attempting to use bzr as an svn client. The svn repository seems to contain some file names which bzr struggles with. The bzr-svn plugin seems to be aware of this limitation because it outputs a "friendly" message:

> bzr: ERROR: Unable to convert Subversion path file with \ backslash because it contains characters invalid in Bazaar.

Whereas using a bzr repository directly (without branching from svn) prints a traceback:

> bzr: ERROR: bzrlib.errors.InvalidEntryName: Invalid entry name: file with \ backslash

As tested on Ubuntu 7.10 (Gutsy Gibbon) with the version of bzr and bzr-svn packaged for that distribution.
