errors don't come back as Content-type: text/html

I'm running a proxy server. If I send it:

GET gopher://nosuchhost HTTP/1.0
Accept: */*

I get

HTTP/1.0 500 Internal error
MIME-Version: 1.0
Server: CERN/3.0pre6
Date: Tuesday, 12-Jul 23:12:26 GMT
Content-Length: 299

but no Content-Type: text/html, although the result starts with
. Is this a bug in the Cern server, or is this a problem with lynx, which interprets it as text/plain instead of text/html? The HTTP documentation I can find online doesn't say whether the default for Content-Type is text/plain, text/html, even though Content-Type is optional.
