This is not actually a problem with KBounce. The high score dialog is provided by libkdegames. Even so, that's really and odd behavior and I think it should be changed. I'll take care of it as soon as I have some time available, unless other people comes first, of course.
Hello André. It seems that I prematurely assumed that the bug resided on libkdegames. It's really a KBounce bug. I sent a patch to revision and will push it to the 4.10 branch as soon as it gets approved. The update will be released on May 7, by KDE. However, end user availability depends on your system's package management.
Git commit 23440210765beb6ff465b5c8809619af829a1e6a by Roney Gomes. Committed on 13/04/2013 at 21:04. Pushed by roneygomes into branch '4.10'. Don't add empty scores to the highscores table. As said in the descprition, this change avoids the inclusion of empty scores, i.e.: when it's equal to zero, in the high scores list. It doesn't make any sense to threat zero as a valid score, let alone write it in the high scores table (which is meant for exposing the player's best matches).
