Segmentation fault possible at transition from finished to new game
By chance I found a segfault in version 3.32.2 (running Linux Mint 20.1, Cinnamon, 64bit):
After finishing a game and closing the highscore window, the game board remains active so that balls can still be selected. So, when I click on a ball in that situation it starts to rotate. When I then start a new game and click on an empty field on the new board (NOT one of the new balls!), the game crashes; running it from a terminal yields the message:
"Segmentation fault (core dumped)"
I only tried this on the 9x9 board, but would guess that this affects other sizes as well. However, it does not really impact any functionality apart from having to start the game again.
