It appears this code isn't capable of dealing with OS version numbers with a nil minor component:

app/models/facts_importer.rb:
 32         major, minor = orel.split(".")
 33         major.gsub!(/\D/,'') unless is_numeric? major
 34         minor.gsub!(/\D/,'') unless is_numeric? minor
 35         minor        ||= ""
