I already stated this during discussions on IRC, but I will reiterate
here to feed the discussion.

The only place where dnspython needs a working /etc/resolv.conf is
testing. Mandating a non-working /etc/resolv.conf will only result in
having less tests in that package, which will potentially lower the
package quality insurance, rather than improving Debian. When addressing
this problem, we should ask ourselves: what is it that we're actually
trying to fix. IMO: not much here... There's nothing broken.

Therefore, I am in the opinion that we should let the package run its
test as much as possible, especially considering that it's not doing
actual network outbound connections.

Cheers,
