[X2Go-Dev] x2go doesnt connect when using chacha ciphers

[bo0od]

i have talked to libssh dev on IRC channel they said libssh supports 
chacha and i have installed x2goclinet v4.1.2.2 with libssh 0.9.4-1 
(both from sid debian repository)

They said x2go might be restricting its ciphers or not using libssh configs.
