brz fast-export fails with TypeError: write() argument must be str, not bytes

[Balint Reczey]

Thank you for maintaining the Breezy!

I'm working on converting on many Bazaar repositories to Git and wanted to give a try to brz replacing bzr [1], but it failed quickly in brz fast-export:

root@cc-daily:~# brz fast-export lp:anna > /dev/null

Thanks for the bug report. This should be a simple thing to fix. In
the mean time, you can specify /dev/stdout explicitly to work around
it:

$ brz fast-export lp:anna /dev/stdout

If you're running bzr fast-export against a remote server, you may
