I can't find anything in dnsmasq's changelog for 2.73 in that regard.
To me that looks like a regression in dnsmasq and should probably be
fixed there.

I've CCed the dnsmasq maintainer, maybe he can comment on this.

If the current usage of --conf-file with an empty parameter was not
officially supported and only working by accident, then this is indeed
something which needs adjustments in NM, otherwise this bug report
should be re-assigned to dnsmasq.

Regards,
Michael
