I was seeing the same thing last November when I was traveling. It only
happened in my hotel room on the broadband connection. 

My suspicion is that the DHCP server is not providing a DNS server and
that it is simply deleting the resolv.conf instead of leaving the
existing one.

You might want to try doing a capture of traffic to the bootps port on
your system and see if that is what is happening.
