I also encounter this bug on fresh Kubuntu 15.04 install. I'm on SSD I don't know if the daemons starting speed has somthing to do with this.
I suppose NM gets the DNS info (from DHCP), tries to notify dnsmasq. Since dnsmasq is not yet started it launches it but I don't see any retry afterwards to send DNS info to dnsmasq once started.
The symptoms for me are working IP stacks (both 4 and 6), correct routing, but with all DNS requests "refused" (by 127.0.1.1).
Restarting NM after makes everything work as expected (dnsmasq is then already started)
How can I see if NM retries to pass the DNS info to dnsmasq once started ?

That's what I get on boot, nothing about NM or dnsmasq after, until I restart NM service.
