[Bug 1046154] [NEW] Can't resolve OpenVPN DNS while using a 3G connection with resolvconf installed

[iox]

Public bug reported:

Ubuntu version: fresh install of Ubuntu 12.04.1 LTS 64 bits (3.2.0-29-generic)
Resolvconf package version: 1.63ubuntu15

What I expected to happen: Connect through 3G (bluetooth DUN), connect
to a OpenVPN and be able to resolve the internal domain names to access
some servers.

What happened instead: I can't resolve internal hostnames.

Additional information: It only breaks when connecting through 3G. When
connecting through Wifi/Cable it works perfectly.

Workaround: Uninstalling the package resolvconf seems to solve the
problem.

Other users probably affected:

network-manager-3g-internet-and-vpn.html

I've looked at other bug reports and tried other solutions:
* #922578.  Removing "resolvconf" is a workaround that works, but I imagine this is resolvconf bug and there must be a more elegant solution.
* #994575. This looks related, but I already have the patched version and it didn't help.
* #924013. I have already checked that my OpenVPN servers are pushing the right information (DNS + DOMAIN) back to the client.

With resolvconf installed: cat /etc/resolv.conf:
    nameserver 195.81.137.130
    nameserver 195.81.155.194
    nameserver 192.168.163.200
    search dummy.intranet

With resolvconf uninstalled: cat /etc/resolv.conf
    domain dummy.intranet
    search dummy.intranet
    nameserver 127.0.0.1

Please tell me if you need any additional information
