Godot Engine animation.play() crash

/* Preamble: the crash seems to be caused by calling SomeAnimationNode.play("animation", -1, -1, false) to play the animation backwards. In my scenario, it was an animation that previously played fine forwards and backwards, but I shortened it to 1 second (from 10s)

gdb output with backtrace:
