NetworkManager connection sharing broken

[Juho Teperi]

Binary package hint: network-manager

Ubuntu 11.04, network-manager 0.8.3+git.20110210t152733.00327fb-0ubuntu2, dnsmasq 2.57-1

I have shared my connection using NetworkManager (IPv4 Settings -> Method: Shared to other computers), however this is not working.
I have attached related parts from syslog with NetworkManager's debug enabled.

Seems to be because new dnsmasq (2.56+, http://www.thekelleys.org.uk/dnsmasq/CHANGELOG) checks if there is junk on its parameters and NetworkManager is sending bogus conf-file.
Related part from nm source: http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/src/dnsmasq-manager/nm-dnsmasq-manager.c#n278

Also I tried to run dnsmasq without bogus conf file and with, here are results:

juho@juho:~$ sudo dnsmasq --keep-in-foreground
^Cjuho@juho:~$ sudo dnsmasq --keep-in-foreground --conf-file /tmp/sdfsdf.conf

dnsmasq: junk found in command line
juho@juho:~$ sudo dnsmasq --keep-in-foreground --conf-file=/tmp/sdfsdf.conf

dnsmasq: cannot read /tmp/sdfsdf.conf: No such file or directory
juho@juho:~$

Should be fixed soon, just sent a patch upstream: http://mail.gnome.org/archives/networkmanager-list/2011-February/msg00138.html
