That's the central question of all end-user systems. :)

There may be good reason to check for specific errors and handle them 
differently.  Or as browsers do, just report them to the user and let 
them figure it out.

How much time to invest in handling specific error conditions will 
depend on the app and the nature of the error.

If the result is empty you should be fine.
