I'd say that the best action when doing a reload is to abort the operation 
if an invalid config file is found, going back to the previous 
configuration.

This will only happen when we add things to the config files that the 
previous daemon version did not support. This should not happen within 
patch releases (i.e., all D-Bus 1.0.x config files should be backwards 
and forwards compatible).
