"Find Pledges" search filters on "status" are not working

I have reproduced this in the demo at: http://d46.demo.civicrm.org/

There is an error when choosing just one or many checkbox filters for "Pledge Status" There is also an error when choosing many checkbox filters for "Pledge Payment Status"

To reproduce:
1) Click "Contributions ... Find Pledges"

2) Click any single (or multiple) checkbox for "Pledge Status". (I chose 'completed')

Now you will see the following error:
Sorry but we are not able to provide this at the moment.
(1) is not of the type Integer

To reproduce the second issue:

1) Click "Contributions ... Find Pledges"

2) Choose multiple checkboxes for "Pledge Payment Status" ( I choose 'Completed' and 'Pending' )

You will see the error: Sorry but we are not able to provide this at the moment.
