For some reason, when you type a word into the search box and it doesn't exist, I'm getting the following error:
The specified CGI application misbehaved by not returning a complete set of HTTP headers.
I'm getting this on http://www.tcervo.com, which is running .72. I tested this before, and it wasn't throwing this error.
My new site, running 1.1-beta, does not throw the error (same host.)
