[slime-devel] Debugging "Lisp connection closed unexpectedly" events?

I'm connecting with latest SLIME CVS (as of tonight) to SBCL 1.0.17
(Fedora 8). I'm trying to use Drakma to snarf the home page of LispForum
(drakma:http-request "http://www.lispforum.com/")

Oddly, when I do so, I get:
"Lisp connection closed unexpectedly: connection broken by remote peer"

This doesn't happen when I try other web pages, however. With others, I
get the text of the web page back as a string. Oddly, it does *not*
happen when connecting to the same page when running SBCL in a term
window as opposed to SLIME.

Any suggestions for where to start looking? My gut says that there is a
particular character or something like that in the page that SWANK can't
return over the channel to SLIME/Emacs. I'm not sure how to debug it,
though, since SWANK kills the connection with extreme prejudice. Does
SWANK create any sort of log file anywhere, or can I enable it to do so?
