In addition to Dereks comment Id like to point out one possible exception:


All front-end / GUI user-event handlers should contain a try/catch/finally block. Never ever will a larger application be free of bugs.  I believe it is absolutely unacceptable and way too risky to let the whole thing crash in such a case. The user must be allowed to continue working, perhaps retry his last steps or move over to another task. And, of course, there must always be a "controlled shutdown" of the application.
