After sumbmission always getting redirected to <front> / front page

Somehow after submitting the forward form the users are always being redirected to the front page and not staying on the recent node where they submitted the form from.

after I commented out this part of forward.module it worked again:

if ($nid == '') {
    $nid = 0;
    $returnurl = '<front>';
  }

I am inserting the forwardform into a cck-node with

print $node->content['forward']['#value']

I tried to send it with using the $body var and the complete output but the same happens?!
