Package: x2goclient
Version: 4.1.2.2

x2goclient stoppped connecting to a working x2go server after some update of
the client on both Linux and Mac boxes.  Provisional fix - The offending
line is "Port 22" in the localhost section of the ~/.ssh/config file on the
client side.  Commenting out the line solves the problem on both Linux and
Mac boxes.  It seems that some parser (no idea if it is the x2goclient's or
the nxproxy's one) is doing some strange thing and gets confused, as the
error message has nothing to do to the port line.  A permanent fix would be
appreciated.

Below are the relevant part of the output from x2goclient --debug and the
content of the ~/.ssh/config file with an offending Port line in the
localhost section:

x2goclient --debug:
