check $c->error in your end action, handle it, then call 
$c->clear_errors to prevent Catalyst generating an error screen. Note 
that in the absence of this so long as your app isn't in debugging mode 
users will see "Please come back later" in lots of languages, not a dump 
of your app's internals.
