Description Sian January CLA 2005-11-25 10:43:03 EST 
If you choose to compare a crosscutting map with the current build for a project, and then delete that project an NPE occurs.  This then also happens for every subsequent build until the view is closed, which is why I have marked it to be fixed for 1.2.1. Stack trace shown below:
