Seems like the if statement is not correct either: If "no-defaults" is
true, then the config file should *not* be read.
Otoh, then you have the opposite problem, if no-defaults is false /
not set, then of course the below code *should* be executed. So you
still need to trace where it is set. (Or maybe it is not set / handled
anywhere?)
