bottle+cherrypy gives ""TypeError: WSGI response header key 'Content-Length' is not a byte string"

I am not sure if this is a bottle or a cherrypy issue, but anyway

I’m using the following configuration:

Arch Linux with 2.6.32-lts kernel hardware: i686 Intel® Atom™ CPU N270 @ 1.60GHz python 3.2 cherrypy-svn 2567-1 bottle 0.9.5

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 error message:

---

Traceback (most recent call last): File “/usr/lib/python3.2/site-packages/bottle.py”, line 743, in wsgi start_response(status, response.headerlist) File “/usr/lib/python3.2/site-packages/cherrypy/wsgiserver/wsgiserver3.py”, line 1846, in start_response 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:
