Crash when villager looks for points of interest

When I poured lava on my villagers (with profession) in creative mode the game crashed. Trying to reload the saved game results in another crash.

My attempt to reproduce create a new customized world  with these presets: minecraft:bedrock,5*minecraft:iron_block;minecraft:plains;

create a 5x5x3 walled area toss in a few profession blocks lectern, fletching table, brewingstand, etc... bunch of villagers (+/- 6) throw in some lava ....

If needed i can supply the savegame(s).
