Comment 6 for bug 916056

ok, so what appears to have happened is that language-pack-gnome-es-base has been updated recently, actually a couple of times starting at 2012-01-04.

Some added translations for onboard in multiple languages replaced single quotes with double arrows, which most likeley triggered this bug. The blame is on onboard of course. We have to be prepared for anything utf-8 the translators give us.

This particular bug seems to affect only version 0.96.1. The current release 0.96.2(in Precise) had some messages upgraded to python 3 style formatting and doesn't appear vulnerable anymore. I'll do some more testing and then I think we should suggest another SRU for Oneiric.
