Yeah.. well.. to prevent tossing, i would simply bummer with message

It is easy to do by applying following pattern everywhere:

replace all calls like
value := getKeyValue( KeyName)
with:
value := getKeyValue( KeyName , defaultValue)

so, there is no chance to get NULL & crash, because returned values
are always valid.

Esteban, it all yours..
I don't have time doing it right now, because i got like 6 other
configs to write :)
