heliotrope-add -m mbox crashes in transcode

[a1exsh]

Just tried importing my old mbox with this command:

ruby -Ilib bin/heliotrope-add -m ~/tmp/mailbox -d data

and got this crash at some point:

The problem appears to be with the html_to_text converter and Locale.current.charset. The latter gives nil on my system, which gets passed to transcode and fails as described above.

Good debugging. I have a fix for this which I will push shortly. Thanks!
