I'm not using url-dav.el -- I'm using xml-rpc.el which I maintain.

However, to eliminate the reliance on external code, I've pulled the bit
from xml-rpc.el that makes the call to post to a weblog hosted on
Blogger.com:

        (let ((url-debug t)) (setq url-request-data "<?xml version=\"1.0\" encoding=\"UTF-8\"?><methodCall><methodName>blogger.newPost</methodName><params><param><value><string>0123456789ABCDEF</string></value></param><param><value><string>9380140</string></value></param><param><value><string>usrname</string></value></param><param><value><string>passwrd</string></value></param><param><value><string>Iñtërnâtiônàlizætiøn from emacs with patch</string></value></param><param><value><boolean>1</boolean></value></param></params></methodCall>")
        
          (setq my-resp (unwind-protect
              (save-excursion
        	(let ((url-working-buffer (get-buffer-create
        				   (xml-rpc-get-temp-buffer-name)))
        	      (url-request-method "POST")
        	      (url-request-coding-system 'utf-8)
        	      (url-http-attempt-keepalives nil)
        	      (url-request-extra-headers (list 
        					  (cons "Content-Type" "text/xml; charset=utf-8"))))
        	  (set-buffer url-working-buffer)
        	  (let ((buffer (url-retrieve-synchronously "http://plant.blogger.com/api/RPC2"))
        		result)
        	    (set-buffer buffer)
        	    (url-http-parse-headers)
        	    (if (> url-http-response-status 299)
        		(error "Error during request: %s"
        		       url-http-response-status))
        	    (url-extract-mime-headers)
        	    (setq result (xml-rpc-request-process-buffer buffer))
        	    result))))))

Without the patch that I supplied, this results in a server error:
"unexpected end of file found"

With the patch, it works perfectly.  The result can be seen at
http://emacs-weblogger.blogspot.com/

(I originally used the LiveJournal platform, but decided it wasn't good
enough for this demonstration since it uses Perl's SOAP::Lite which is
very liberal in what it accepts.  Blogger.com runs on Java and Java's
static typing makes it stricter in what it will accept when it comes to
XML-RPC types.)

For purposes of this report, I've attached a .zip file with my a elisp
snippets, a perl snippet and some packet traces of the working and
non-working code.  I've elided my username and password, but you'll be
able to see that the server fails when I submit without the patch and
succeeds when I submit with the patch.

Further, the only differences in the packet traces are the way
"Iñtërnâtiônàlizætiøn" is encoded and the Content-Length header.

I'm fully prepared to admit that my patch only works in this case
because of some fluke, but the fact is that url-http.el works with the
patch and fails without it.  I humbly ask your assistance in fixing
url-http.el.
