Comment 5 for bug 522154

Ah, I found out the problem: the template needed to have the "Include translations for this template in language packs?" checkbox checked in the admin form.

The translations should now be exported and built in the next round of language packs which pick up this.

In the meantime, could anyone test if the current package and a computerjanitor.mo file fixes this?

I.e. just download the .mo file manually from e.g. https://translations.edge.launchpad.net/ubuntu/lucid/+source/computer-janitor/+pots/computerjanitor/es/+export (substitute es for your language) and copy it to /usr/share/locale-langpack/es/LC_MESSAGES
