The most likely cause is that gnubg couldn't contact random.org when it tried to pull the second batch of dice. Does it happen consistently ? If not, does your machine have internet access when it does ? FWIW, I couldn't reproduce the problem with the current gnubg version (and not on linux Mint ; the random.org related code hasn't changed since 1.06.001, but the system library used to establish connections is almost certainly at a different version).
