The bzr plug echoes "added: somefile.mdwn" when it adds somefile.mdwn to the repository. As a result, the redirect performed after a new article is created fails because the bzr output comes before the HTTP headers.

The fix is simply to call bzr with the --quiet switch. Something like this applied to bzr.pm works for me:

46c46
<   my @cmdline = ("bzr", $config{srcdir}, "update");
---
>   my @cmdline = ("bzr", "update", "--quiet", $config{srcdir});
74c74
<   my @cmdline = ("bzr", "commit", "-m", $message, "--author", $user,
---
>   my @cmdline = ("bzr", "commit", "--quiet", "-m", $message, "--author", $user, 
86c86
<   my @cmdline = ("bzr", "add", "$config{srcdir}/$file");
---
>   my @cmdline = ("bzr", "add", "--quiet", "$config{srcdir}/$file");

>   eval q{use CGI 'escapeHTML'};
>   error($@) if $@;

done, although I left off the escapeHTML thing which seems to be in your patch by accident.
