Description Grant Gayed

3.7M2 test build
- observed on Linux-motif, but presumably affects other platforms as well

I could not find reproducable steps for this, but I'm pretty sure it happened while either dragging a resource within the Package Explorer, or deleting a resource there by pressing Delete.  The stack follows.

Fixed the NPE in HEAD. A test case would be good though.
