CiviPledge crashes on first pledge.

The addition of the first pledge for a new donor causes the program to crash, with an error in line 411 of CRM/pledge/BAO/payment.php.

The parameter {$paymentStatusId} is null and should have a value of 2.

The problem was traced to line 178 of the same file where the function self::updatePledgePaymentStatus( $params['pledge_id'] ); is called.

It is obvious from the implementation of the function that it should also receive at least the $paymentStatusID parameter, because it is needed for the function

updatePledgePayments( $pledgeID, $paymentStatusID, $paymentIDs ) on line 324, which will not accept a null value for the second parameter.

I was able to solve the problem by changing line 178 to:

self::updatePledgePaymentStatus( $params['pledge_id'],$paymentIDs,$paymentStatusID,$params['status_id']);

This may not be the best solution, as I'm not quite sure about the other cases involved, but at least it works!
