This looks to me as if your CGI blurted out the following,
literally:
 "An error occurred while perfor:/data/webmaster/homesite/cgi-bin/contents.cgi"

... instead of emitting a proper header.  What software element
associated with your CGI would say "An error occurred while..."
In other words, I'm saying that "An error...cgi-bin/contents.cgi"
IS the "malformed header" that Apache is objecting to.

If you'll send me relevant portions of "contents.cgi", I'd be happy
to look it over for you.  (I just spent most of the day digging for
a really dumb CGI bug.  I was both successful and suitably humbled.)
