[issue1656] Convert bzr repo with an exclude filemap specified raises exception

[Gary Herron]

New submission from Gary Herron <gherron at digipen.edu>:

Converting a bzr repository with a --filemap containing an exclude
causes a exception

Using the latest version (as of May 12 2009) of convert:
  http://hg.intevation.org/mercurial/crew-stable/rev/13b36eb14324
and the latest mercurial on Ubuntu (version 1.1.2).

Here's a small command line sequence that produces a bzr repo,
creates a file for --filemap, and converts it.  
The traceback follows.

rm -rf hg-break bzr-break

mkdir bzr-break
cd bzr-break
bzr init
mkdir a
echo a > a/a1
echo a > a/a2
bzr add a a/a1 a/a2
bzr commit -m 'init'

cd ..
echo exclude a/a1 > fmap
hg convert -d hg -s bzr --filemap fmap bzr-break hg-break

Traceback:
