Can't get default tid of userpoints categories

When you go to "My Account" page, the "Points" is always zero. I found it is caused by one bug in userpoins.module at 1779:

/*
* Wrapper function to return the default tid via API call
*/
function userpoints_get_default_tid() {
variable_get(USERPOINTS_CATEGORY_DEFAULT_TID, NULL);
}

Apparently, it needs a "return". The correct code should be as the following:
