Hi,
A non-maintainer upload (NMU) will happen on strongswan pretty soon, in order to fix some pending bugs related to localization (most often new or updated translations).
A round of translation updates is being launched to give all translators a chance to get their translations in for that package.
Please send the updated file as a wishlist bug against the package.
The deadline for receiving the updated translation is Tuesday, November 16, 2010.
Thanks,
