Apparently this has been fixed upstream in glibc:
http://sourceware.org/bugzilla/show_bug.cgi?id=15339
There's also a related discussion at

... that there is something abnormal with this Ubuntu release.
no, it is not. This has nothing to do with Ubuntu, but is an upstream change
introduced with glibc-2.17. So you will see it on every system which is based
on the glibc version.

I have the same problem. Reproduced via custom app and what's failing is:
getaddrinfo(some.invalid.address.here, NULL, hints, result);
And it's failing quickly. But the returned error is system error 110
(Connection timed out).

Yavor added the comment:
* Up-to-date Arch Linux: -2 - Name or service not known
* Fedora Live CD: -2 - Name or service not known
These are in general with more recent libraries/packages than Ubuntu 13.04. All

would be good to know if this is related to glibc-2.17, or not. There was a
similiar issue ...

I can't see how this could be classed as a bug in Python. An invalid domain
should quickly return a DNS error on a correctly configured operating system,
which is what the test is testing. If this report came from less well know
names, I'd just close the
