pygame.sprite.GroupSingle
Hi,
Yes Tobias, that is right. GroupSingle.draw is inherited from AbstractGroup, which adds each sprite drawn to the spritedict dictionary. It is a bug, though technically not a memory leak since the sprites are still referenced.

The spritedict dictionary is not emptied by GroupSingle, so a reference to each newly-created sprite remains even after a new sprite has been put into GroupSingle. I'll have to test my theory before I'm certain though. If that's the problem, then I'll fix it.
