All reports of misnamed-po-file for the archive. The extended description of this tag is:
The name of this PO file doesn't appear to be a valid language code. Any files in debian/po ending in .po will be processed as translations by po2debconf for the language code equal to the file name without the trailing .po. If the file name does not correctly reflect the language of the translation, the translation will not be accessible to users of that language.
If this file isn't actually a PO file, rename it to something that doesn't end in .po or move it to another directory so that translation merging programs will not be confused.
Severity: normal, Certainty: possible
Check: po-debconf, Type: source
