While comparing outgoing changes, I decided to perform an edit in the compare 
view, and got the following stack trace (and an error dialog):

Comment 1 Mike Wilson CLA 2001-11-19 14:32:18 EST 
The "Failed to execute runnable" exceptions are just SWT trying to be helpful 
by notifying you that a problem occurred while a runnable was being executed 
by the u/i thread on behalf of the application. You need to look down the 
stack trace to find out what the real problem is. In this case, a NPE in the 
jface.text ContentAssistant.
