I am experiencing several (presumably related) crashes to desktop, which I believe to be related to tooltip rendering. The crash occurs when I mouse over an object in Inventory. I suspected it was due to a config change I had made, as I had just disabled a number of blocks in objects.cfg.

I tried:
-Crash: Only Architect, Builder, Filler, Frame, Library, Quarry, Zone Planner, Filling Planner, and Snapshot set to false (original configuration)
-Crash: Only Builder, Filler, Frame, Library, Quarry, Zone Planner, Filling Planner, and Snapshot set to false
-Crash: Only Filler, Frame, Library, Quarry, Zone Planner, Filling Planner, and Snapshot set to false
-Crash: Only Frame, Library, Quarry, Zone Planner, Filling Planner, and Snapshot set to false
-Crash: Only Library, Quarry, Zone Planner, Filling Planner, and Snapshot set to false
-Crash: Only Quarry, Zone Planner, Filling Planner, and Snapshot set to false
-Crash: Only Zone Planner, Filling Planner, and Snapshot set to false
-Crash: Only Filling Planner and Snapshot set to false
-Crash: Only Snapshot set to false
-No Crash: All set to true
-No Crash: Only Architect, Builder, Filler, Frame, Library, Quarry, Zone Planner, and Filling Planner set to false

Based on this, I believe that disabling Snapshot in objects.cfg causes the client to crash to desktop when an inventory item would display its tooltip.

Some additional elements I tested:
-In Survival/Adventure mode, the crash occurs upon mousing over an object in Inventory (tested with Dirt Block, Slimeball, Raw Chicken). In Creative mode, the crash occurs immediately, presumably because the mouse defaults over an object in the Creative Inventory.
-The crash occurs whether mousing over an item in Inventory, or in a Chest.
-The crash occurs both in a Single Player world, and on a Multi Player server.
-The crash occurs when BuildCraft is the only mod present (other than Forge; not sure if that counts).
-The crash occurs whether Debug Tooltips are shown or hidden.

For clarity, this was
-Minecraft 1.11.2
-Forge 13.20.1.2386
-MultiMC 0.5.0-945
-BuildCraft 7.99.6

Please find attached the crash report that Forge (or maybe MultiMC?) generated, and the config file that should reproduce the error (as a .txt file because GitHub wouldn't let me upload the file otherwise).
