I've verified with Ethereal 0.9.15, on Linux, that "ip.addr ==
www.mit.edu" works as a valid display filter. It appears that Ethereal
is unable to resolve "www.mit.edu" on your machine, because if I put an
invalid hostname in the display filter, I get the same error as you.

If you go to a command prompt on your machine and type "ping
www.mit.edu", does it attempt to ping an IP address?
