This should be already fixed in the library as mentioned by the
maintainer in this[0] thread. Adding Paul Moore in CC. There's also a
bug entry on launchpad[1] for that. I provided the patch (before the
pull reuqest) requesting for some review and testing but never heard
back again. Also CC'ing Karl-Philipp Richter (bug owner) for some
opinions on that as well.
