[mew-int 2987] display html mail with w3m

Hallo,

I just upgraded to Ubuntu natty 11.04 with emacs 23.2 and mew 6.3.
I have w3m and w3m.el installed and I use my .mew and .emacs that used to work
fine in Ubuntu 10.04. But now html mails are not rendered in the message
buffer.
Is this a problem with emacs 23.
I could see that w3m-e22.el changed to w3m-ems.el could this be the problem?

Any help is highly appreciated

Yours, martin
