I tried to summon a particle with the name "fallingdust" via an AreaEffectCloud (AEC), but it crashed my game every time I tried (crash files attached, as well as the game output).

It does not happen with the name e.g. falling_dust or fantasyname, only with the name fallingdust.

Steps to Reproduce:
Use this summon command:

/summon AreaEffectCloud ~ ~1 ~ {Particle:fallingdust,Radius:2f,Duration:600}

It says "Object successfully summoned" in the chat, but then your client crashes.

Use e.g.

/summon AreaEffectCloud ~ ~1 ~ {Particle:fantasyname,Radius:2f,Duration:600}

and it will default back to its regular mobSpell-particle.

Without a Radius it does not crash (probably because the particle doesn't get generated):

/summon AreaEffectCloud ~ ~1 ~ {Particle:fallingdust,Duration:600}

Edit: Probably needs to have an ID of the block added to the command to not crash, but in any case the above command shouldn't crash as well, even though it might be probably wrong }=)

^{Sorry if it got already reported, I'm bad in finding them };]}
