Your baby might get stuck a few times but she will learn how to move her legs in such a way to free herself. Until then you might have to rescue her. As she becomes more and more mobile, you have to be concerned about her using the bumpers as a stepping stool to reach and climb. I wouldn't worry about bone fractures from getting legs caught in the slats rather the dangers of her climbing/reaching for things that could pose a more serious danger.
