I would say the opposite. In production code usually I want it
to recover, log as much information as I need (including sending
any notifications), and NOT just die.

In development, not catching the exception will give me a full 
trace back automatically. Why bother with trying to catch and 
print something when the interpreter will do it for me? Not
to mention that removes any hassle of trying to catch the
"right" exception or figuring out the best way to print it.
I suppose if there are arguments on the exception that were not
printed then I might want to catch it, but has been rare
in my experience.
