[Tails-l10n] Mangled titles in the News column

Hi,

the titles of the entries in the News column on the front-page
tails.boum.org are mangled in all but the English version of the page.
E.g. 'Tails 1.2.3 is out' is '\"Tails' in the de, fr, pt versions.
I can't reproduce this with a locally build wiki.

Anybody any idea how to fix this?
