Um. For interactive applications with valuable state, you should have  
a general (handler-case ... (error ...)) around each turn of your  
event loop/command loop/whatever, for exactly this reason.

In systems of today's complexity, you can't foresee *every* error case  
whether or not they're expressed as exceptions, and having a general  
ERROR handler (perhaps with a warning to the user) is a simple and  
effective approach.
