Po-generated parts of www.debian.org broken in some languages

Hi,

Pages in www.debian.org are currently partly broken; po-generated
parts of pages, such as side bars and release dates, are not localized
in some languages.

According to my manual incomplete check, po-generated strings are
- correctly localized in Danish, Finnish, French, German, and Russian,
- and not localized in Catalan, Dutch, Japanese, Korean, Polish,
  Portuguese, and Spanish.

Wml-generated parts (I mean translations directly written in wml) are
properly localized.

Do you have any idea what caused this issue?

Thanks,

-nori
