`mismatch-translated-choices`

A "Choices:" field is a comma separated list, and translated "Choices:" fields must have the exact same number of elements. One of the translations does not follow this rule, you should contact the translator and request for a new translation where elements of "Choices:" fields have no embedded commas.

Cdebconf understands escaped commas in such fields, but packages outside the scope of debian-installer must not have them until they are also supported by debconf.
