gnubg does not start/work

Until yesterday, I used Leap 42.3 and ran gnubg perfectly. Now I installed gnubg from the common repositories and it won’t start and it won’t say nothing even at the command-line terminal.

I confirm the same problem.
Gnubg doesn’t start. It consumes 25% of CPU power with nothing on the screen.
Command line doesn’t show anything, not at all.

And their website is offline (yesterday and today)
