MaxScale fails to start and doesn't log any useful message when there are spurious characters in the config file

In maxscale.cnf, if I add anywhere:

....
any_string_without_equal_sign
....

MaxScale refuses to start but in the error log there is no evidence of misconfiguration:

May 10 18:38:10 dhcppc6 maxscale[2187]: Finished MaxScale log flusher.
May 10 18:38:11 dhcppc6 maxscale[2187]: MaxScale received signal SIGTERM. Exiting.
May 10 18:38:11 dhcppc6 maxscale[2187]: MaxScale is shutting down.
May 10 18:38:11 dhcppc6 maxscale[2187]: MaxScale shutdown completed.

I think MaxScale should point out at the misconfiguration.

While if you add an option like:

....
blah=123
....

It starts but doesn't complain at all.
