greg sync crashes when run from (f)cron

[josswright]

I've got a simple greg sync running as a cron job (via fcron under Arch Linux). It works fine when I run it in the terminal, but when running as a cron job I get the following output:

Traceback (most recent call last):

Hi, this is most likely because $LANG is not set in the cron environment. Try setting $LANG in your crontab file to whatever you get when doing echo $LANG in the terminal.

Excellent. Thank you!

Check it out, and please close the issue if this solves it. I should probably add a troubleshooting section to the README...

Seems to work. Thank you! Annoyingly, when I checked, I had already had to do that for another cron job running a python script, so I really should have known already. (The other program was vdirsyncer, in case anyone stumbles across this.)
