Yes, I should have thought about it. ldd showed that dbus-daemon used an old libexpat1 of another software. I changed the order in /etc/ld.so.conf.d and now all works fine. I do not know why it happened because the machine is very stable and I apply only security updates, and I do not update the guilty software for years. Please accept my apologies for wasting your time. Many thanks for the help. Alberto > > smcv
