Why is Godo crashing when I try to restart a one-shot particle emitter?

Question

So, here's what I'm trying to do: I'm using a particle emitter with the one_shot flag enabled to show an actor attacking, i.e., shooting a partincle in the direction of a target. Then the actor reloads (i.e., waits a number of seconds) and to shoot again it should activate the emitter again.

This is the code that shoots once:

if not attackOrigin.emitting:
        attackOrigin.restart()
        attackOrigin.emitting = true

As I said, it works once. Then when the loop runs again it not only fails to emit the particle, but it also crashes without an error. The debugger is showing me this:

:100">

I'm using Godot 3.1.1 on a Mac, and I am also sure that the time when I fire the emitter again is larger than the lifetime of the particles. Is there a better way to do this than creating an emitter tha destroys itself after it's done, or just setting my emission frequency to the frequency of shots I want (which would not only make it impossible to have a variable rate, but also it'd make it impossible to have more than one shot at once)?
