[Bug 1822463] Re: autojack crashed with ValueError in start_slave(): not enough values to unpack (expected 3, got 1)

[Ross Gammon]

Well, so far the problem is pretty limited, and only those with the
older us-controls sticking with DEV=default would experience the bug.
And the simple work-around is to update to the fixed version in the ppa,
re-save the configuration, and autojack should be happy after that.

I just ran autojack with the latest us-controls in the autobuilder, and got this new crash (I did not change my autojackrc which had been left with "DEV=default"):
$ autojack -h
