There is a bug in the code for checking a major standards version increment. For example, the page for Unifont (https://packages.qa.debian.org/u/unifont.html) contains this item in the "Problem" section:
"The package is severly out of date with respect to the Debian Policy. Latest version is 3.9.8 and your package only follows 4.0.0..." Note also the misspelling of "severely" as "severly". The new tracker spells this correctly. Paul Hardy
