Comment (by vorner):

 Well, I'm not sure if it should or should not crash, since the unreadable
 certificate is quite fatal for it. Have it there, sitting and doing
 nothing is
 not useful and crashing may at least bring the admin to the place where to
 look. But I agree this should have a better error message with
 explanation.

 As with the bindctl, I don't know. It tries to connect, the connection
 succeeds
 and then, after some initial hello messages the remote just drops the
 connection (because it crashes, but it has little other choice than to
 drop it
 when it can't read the cert file). So here it should probably say just
 that the
 other side closed the socket at the wrong moment and suggest looking into
 the
 log if cmdctl is OK.
