camel-cxf content-type response header

[Marc Giger]

Hi all,

I'm missing the content-type http response header in camel-cxf 1.6 
(cxf:bean:localEndpoint?dataFormat=MESSAGE)

HTTP/1.1 200 OK
Content-Length: 4648
Server: Jetty(6.1.10)

or

HTTP/1.1 500 Internal Server Error
Content-Length: 253
Server: Jetty(6.1.10)

What do I have to do to get it back?:-)
I've lost the overview...

Thanks a lot!

Marc
