I'm using the following configuration:


Arch Linux with 2.6.32-lts kernel[[BR]]
hardware: i686 Intel(R) Atom(TM) CPU N270 @ 1.60GHz[[BR]]
python 3.2[[BR]]
cherrypy-svn 2567-1 [[BR]]
bottle 0.9.5[[BR]]

Both a Bottle and a Cherrypy 'hello world' run fine. But when I try to run
Bottle with Cherrypy like this:

{{{
from bottle import route, run

@route('/')
def hello():
return 'hello world'

run(server='cherrypy',host='192.168.1.5', port=8080)
}}}

I get this errormessage:

{{{

raise TypeError("WSGI response header key %r is not a byte string." %
k)
TypeError: WSGI response header key 'Content-Length' is not a byte string.

During handling of the above exception, another exception occurred:
