Font error at the mainframe

Hello:

With my new upgrading to amd64 debian8 I can't  any more access the
graphical nodes at our national computing center. It should be a problem
with my box. At my terminal

francesco@tya64:~/servers/cineca/RCM_remote_visualization$ ./RCM_linux_64bit
> setting verbosity to: 0
> deleting fontconfig
> log file folder: /home/francesco/.rcm/logs
> Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70:
> non-double matrix element
> Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70:
> non-double matrix element
> Fontconfig warning: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line
> 78: saw unknown, expected number
>

whereby the graphical nodes appear to be IDLE

thanks for help
