GreenHopper Total Estimate Calculations Going Wrong

Steps to Reproduce:

1. Create a new scrum board with stories more than 50
2. Have Story Points for all of them with decimal values (say 5.1)
3. Create Sprint to include all these stories so that the values goes above 240

Expected Results:

1. The correct sum of the estimates are shown in the Estimate field

Actual Results:

1. The Estimate will start showing up wrong values (an extra 2000 gets added)
