sure, well it couldn't be much simpler, which means i guess it should
always happen:

(in-package :it.bese.ucw-user)

(defcomponent hello-world (simple-window-component) ()
             (:default-initargs :title "hi")
             (:render () (<:as-html "hello world")))

Which outputs the beforementioned error. My guess was you wrote that
*trace-output* should be bivalent. And slime says it's stream is a
character stream. e.g. that's the reason it breaks on:

(WRITE-SEQUENCE #(72 84 84 80 47 49 46 49 32) *standard-output*)

which is called in http-send-headers which is called by send-response.
So i guess it makes sense. Now, unless there is a really easy way to
change the slime stream to a bivalent stream (which i guess there is,
although i searched hard) and if my assumptions are right, i would
rather not have send-response being called, since most people (read
"I") use slime. Or...
