xboard 4.9.1 + gnuchess 6.7.2 don't work together

[Fr Ml]

Hello,

Xboard 4.9.1 doesn't work with GNU Chess 6.7.2 (archlinux machine).
If I'm white, it just makes one move and then after my second move it does nothing.
I've asked Xboard (bug-xboard@gnu.org) about this problem but they say, it's a GNU Chess problem.

So I don't know. Somehow the interaction between the two programs doesn't work?

I've attached the debug file:`xboard -debug`

Regards
Frank
