Descrption: doing "go test" with the modules mention in go.mod -> everything works
            doing "go test" with the newest modules in Debian  -> everything works
            running the test on the buildd                     -> everything works
            running the test manually with autopkgtest         -> failure
            As autopkgtest uses locale C and everything else something like *.UTF-8
            I assume this is a locale problem
