Hi, These are bugs. If you set G_DEBUG=fatal-criticals, then glib will core-dump for such assertion failures. You can also set [main] debug+=fatal-warnings in NetworkManager.conf Make sure to install debugging symbols, and get a backtrace. It might be simpliest to run NM under gdb (with --debug to keep it in forground). best, Thomas
