Which sounds scary, but perhaps I mis-interpret the situation. :-) There is now also feedback from Armin and Gabor, I would suggest to continue the discussion at <https://gerrit.libreoffice.org/c/core/+/141865> to keep everything at a single place. And sorry for the problem, I was not aware that Ubuntu is shipping an old NSS which is so old that even RHEL7 counts as "new". Thanks, Miklos
