When trying to view help text for any of bzr's subcommands, it errors out like so:


---SNIP---

----SNIP----


This only occurs with bzr-1.4.0, which is the current version in the Ports tree. Downgrading to a previous version (such as v2.3.0) does not exhibit this problem.
>How-To-Repeat:
$ cd /usr/ports/devel/bazaar-ng
# make install
$ bzr update --help
