"An internal error occurred while showing an internal error"

What a great error-message showed up while doing some trivial work with eclipse helios! It made me think about recursions (remember: before you can understand recursions you first need to understand recursions).
My first reaction on the question "Do you want to exit the workbench?" was (after making a screenshot) pressing "No". I hoped to see an error-message like that: "An internal error occurred while showing an internal error while showing an internal error".
But i did not see that message - eclipse presented the "white bar of death" and silently stopped working ...
