Drupal 6 patch : user edit page

This patch is actually for the Drupal 6 version of the module which I downloaded via CVS, but for which there's no CVS tag to create an issue against :(

When a user is not a netForum user, some errors are displayed on the user edit page, e.g.

    * warning: array_keys() [function.array-keys]: The first argument should be an array in modules/user/user.module on line 1498.
    * warning: Invalid argument supplied for foreach() in includes/form.inc on line 1205.

The attached patch fixes this problem and correctly loads the user data.

Cheers,
Stella
