Mac appstore rejection due to resolv.conf access

I’ve just had an update to the Mac app store rejected with this error from apple:

2.30: Apps that do not comply with the Mac OS X File System documentation will be rejected
2.30

The application accesses the following location(s):

‘/private/var/run/resolv.conf’

Nothing I know of accesses this, any ideas what could be the cause?
One of the changes I made in this version was a call to WWW could this be the culprit?

Bump! Nobody? Anybody?
