Problem:
An error dialog shows up with the text "Null".  Clicking on Details shows a "java.lang.NullPointerException".  An exception appears in the log.  The diagram prints out as expected.

Expected:
There should be no exceptions in the log


Steps:
1. Switch to the modeling perspective
2. Create a new UML project and blank model
3. Create a new class diagram
4. Add several classes to the diagram
5. With the diagram in focus, select File->Print.
6. Keep the defaults, click on Ok

Stack Trace:
java.lang.NullPointerException
