Crash if QMI does not support IPv6 nm:ERROR:src/core/devices/wwan/nm-modem.c:209:nm_modem_emit_signal_new_config: assertion failed: (!do_auto || addr_family == AF_INET6)

Summary

NM Crashes upon trying to connect to mobile network with usb stick.

Version affected

NetworkManager (version 1.45.90)

Steps to reproduce

• Connect

• If QMI does not support responding to IPv6 (possible, this dongle is quite old), Network-Manager should at least not crash and just continue with ip4-only connection
