Comment 10 for bug 689286

Just got another Null pointer exception. I was attempting to copy a partitioned graph to a new workspace, hoping it would lead to an eventual work around. I got this error, and was able to pull up the stack trace:

A java.lang.NullPointerException exception has occurred.
However, the system should continue working without further problems.
