Really?  That would be a bug in itself, command_not_found_handler is
supposed to run after forking.

% command_not_found_handler() { print OOPS }
% thisisnotacommand
OOPS
% thisisnotacommand > /dev/null 2>&1
% echo $?
0
% command_not_found_handler() { print OOPS; return 127 }
% thisisnotacommand > /dev/null 2>&1
% echo $?
127

So the actual problem could be that the command_not_found_handler
function is returning zero, making it appear to the "if" that
chckconfig works when in fact it does not.

It probably should be disabled in completion.  No opinion on other contexts.
