Package: nx-libs
Version: 3.5.99.26-3

When I connected to the X2go server, the session was killed abruptly. I
found the X2go server log. It showed that x2goagent hit SEGFAULT.

I got the coredump:

Core was generated by `x2goagent -nolisten tcp -nolisten tcp -dpi 96 -D
> -auth /home/Ricky/.Xauthority'.
> Program terminated with signal SIGSEGV, Segmentation fault.
