I have encountered a strange error message when I try to load certain pages of my site (most pages, actually) on my test production server.
Started GET "/students" for 10.0.0.68 at Mon Sep 17 12:53:16 +0100 2012

Whichever page it happens on the error message is always the same (same line and col numbers) but the filenames are different and the quoted code changes too. As far as I know or can see there are none of these japanese characters anywhere in my code. It seems like some encoding issue or something but I really have no idea and I don’t know where to begin to debug it.

Update: OK, I narrowed the problem down somewhat. Figured out it’s to do with the method call t(:class), which is a rails helper method for translation, and that appears in my views quite a bit (I’m new to this app, so still getting my head around how it’s written). Judging by the two locale files that are present, this is meant to return either ‘School’, or ‘Class’ depending on the locale setting. What I still don’t know is why it is causing this error, though.
@Hates_ solved this one for me in a comment, so I’ll copy what he put to here so that I can accept it as an answer:
