profile module does not handle updates correctly

in the user managment screen, when performing block/unblock on a user the profile fields are erased.
this is due to a bug in the profile save function which is also called on the hook_user update event.
the function assumes that the $edit field is not empty and contains all the relevant fields, which is incorrect. (for example when the user_operations calls
the user_save method, it only provides the status field the has changed).

the fix i suggest would be creating another function to handle updates as follows or simply make these changes to the save function (simple fix which takes the field value from the user account
if not exist in the $edit array):
function profile_update_profile(&$edit, &$user, $category, $register = FALSE) {
$result = _profile_get_fields($category, $register);
while ($field = db_fetch_object($result)) {
if(isset($edit[$field->name]))
$val = $edit[$field->name];
else
$val = $user->{$field->name};
if (_profile_field_serialize($field->type))
$val = serialize($val);
db_query("DELETE FROM {profile_values} WHERE fid = %d AND uid = %d", $field->fid, $user->uid);
db_query("INSERT INTO {profile_values} (fid, uid, value) VALUES (%d, %d, '%s')", $field->fid, $user->uid, $val);
// Mark field as handled (prevents saving to user->data).
$edit[$field->name] = NULL;
}
}
