It is not an error in Emacs or debbugs-gnu.el. It seems to be an error
of the debbugs server on debbugs.gnu.org.

If I raise a search for ruby or alike, the returned HTTP headers are
wrong:

HTTP/1.1 200 OK
Date: Fri, 03 Jan 2014 08:48:44 GMT
Server: Apache/2.2.22 (Debian)
 </value></item><item><key xsi: type="

Content-Length: 1162378
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: multipart/related; type="text/xml"; start="<main_envelope>"; boundary="----

With any other search string, the returned HTTP headers look correctly:

HTTP/1.1 200 OK
Date: Fri, 03 Jan 2014 08:54:55 GMT
Server: Apache/2.2.22 (Debian)
SOAPServer: SOAP::Lite/Perl/0.714
Vary: Accept-Encoding
Content-Encoding: gzip
Connection: close
Content-Type: text/xml; charset=utf-8

I'm worrying about the fourth line, which looks like XML. Maybe it is
unrelated, and the problem are rather the different Keep-Alive states.

I will continue to investigate on debbugs.gnu.org. This will take time.

Best regards, Michael.
