Using a Stink Bottle with a Dispenser while Quark is installed crashes the game with the attached crash log. This was tested on a fresh install of Forge 43.1.38 with only Quark, Alex's Mobs, and their respective dependencies installed. Definitely due to Quark's automation module enabling Dispensers to place blocks, which Stink in a Bottle is technically a block item for Skunk Stink.

Strangely enough, upon reloading the world, the Stink is placed down on the floor normally in front of the Dispenser. If there is no block on the floor in front of the Dispenser, the Stink is placed up against the Dispenser's front face.

Reproduction:
1: Enter a new world with the two mods installed, and place a Dispenser. Place Stink in a Bottle in the Dispenser.
2: Activate the Dispenser. Game will crash. ):
