Description Peter Lam 2008-09-09 00:10:14 UTC 
build 20080908.

This should be a regression somewhere. NPE did not occur in previous builds when tested.

- create a class diagram
- create and name an interface element
- right click on the interface and select Show->As Icon
- copy the iconic interface and paste it on the same diagram
- create a new class diagram
- paste the copied buffer to the new class diagram throws the following NPE. AssertionError was also thrown. See ide log
for complete exception.

This might be a regression from fix in issue 137774 since this problem was not in build 20080904.
