When I throw a custom lingering potion given with the following command:

give @a[x=398,y=4,z=6,r=1,m=2] lingering_potion 2 0 {CustomPotionEffects:[{Id:15,Amplifier:0,Duration:60}],display:{Name:"Smoke Bomb",Lore:[Creates a cloud of smoke.  Players, who walk through it will also be blinded.]}}

the game crashes with the attached report. Oddly enough, it only seems to happen with these specific potions; other lingering potions work fine, even ones with a custom name, lore, and potion effect.

(And for those who are wondering, yes, the potions are for a minigame.)
