Lintian tag information: malformed-changes-file (type: error)

Description (from lintian-explain-tags)

There is no "Format" field in your .changes file. This probably indicates
some serious problem with the file. Perhaps it's not actually a changes
file, or it's not in the proper format, or it's PGP-signed twice.

Since Lintian was unable to parse this .changes file, any further checks
on it were skipped.

Please refer to Debian changes files – .changes (Section 5.5) in the
Debian Policy Manual for details.
