Meanwhile my laptop has been working fine with two dnsmasq instances running in cascade. I'll try to subject this arrangement to more severe tests in the coming weeks.

That breaks the default bind9 and dnsmasq installations, for people that actually want to install a DNS server. Having to manually comment out "#dns=dnsmasq" in /etc/NetworkManager/NetworkManager.conf doesn't sound good, and if it stays that way, it should be moved to the bind9 and dnsmasq postinst scripts. Please make network-manager smarter so that it checks if bind9 or dnsmasq are installed, so that it doesn't start the local resolver in that case.
