Invalid parameters from muptiptart/form-data form sended with Maemo Browser #

How to reproduce

rails test
cd test/
./script/generate controller test index
cat > app/views/test/index.html.erb << EOF
<html>
<head>
</head>
<body>
<form method="post" enctype="multipart/form-data">
<input type="hidden" name="authenticity_token" value="<%= form_authenticity_token %>" />
<input type="submit" value="submit" />
</form>
</body>
</html>
EOF
./script/server -b 192.168.1.10

Now you need to brows to http://192.168.1.10:3000/test/index with maemo browser and press submit button, and you get InvalidAuthenticityToken and this as a parameter list:

Parameters: {"authenticity_token"=>#<File:/tmp/RackMultipart20091119-15972-7huy2e-0>}

With firefox or IE or opera:

Parameters: {"authenticity_token"=>"FgGZ+7GZ+jEcOOAoAa0Cx7ExgghWDtxFUe8VWlVyQLU="}
