Notice: Object of class stdClass could not be converted to int in drupal_write_record() when user pictures are enabled

When the user logs in, $user->picture is set to an object. When remember_me_user_login() sends $account to drupal_write_record(), the latter tries to cast the picture column to an int, as it's expecting $user->picture to be an int, the picture fid, not the full object. THIS CAUSES THE VALUE OF picture to loose the fid and therefor leads to loss of data: the users's picture fid is lost.

One solution would be to replace $user->picture as an object with $user->picture->fid inside of remember_me_user_login().
