Redmine variables not being replaced

I recently moved my redmine installation to a new server and for some reason the variables aren't being replaced any more. For example, this is what I see for the issue tracking:

Bug: 0 open / {{total}}
Feature: 0 open / {{total}}
Support: 0 open / {{total}}
Maintenance: 0 open / {{total}}

This is happening all 开发者_运维技巧over my install, can't figure it out! Thought it could be a db charset issue but changed it to UTF-8 (from latin), restarted passenger and still no luck.

Any ideas gratefully received!

It looks like this is an issue with the most recent version of the i18n gem. See bug#7534 for instructions.
