Error in Batch Contribution update via profile

Bug posted on: http://forum.civicrm.org/index.php/topic,2571.0/topicseen.html

When I try to update a batch of contribution to the Completed status using the Core function, I get an error:

Code:

The value of total_amount is correct (162.50) while the value of net_amount isn't (162,5). This has probably to do with the currency settings (in the Netherlands 162,50 would be correct, but this should be translated back before firing a database query).
