Do you have an example of where this happens? Any steps to reproduce?

Requested a new mylyn that shows the bug happening. The stack trace is out of date compared to HEAD of Cocoa SWT.

The only way this can happen is if the shell was disposed, so I'm checking in a fix that should take care of it. Reopen it if you still hit this, but It's now in HEAD > 20110119.
I verified this with 3.7 N20110119-2000 Thanks!!!
