Crashes in debug world

There is an issue in the debug world where it will crash due to an excessive number of entities.

Step 1: Create a debug world.
Step 2: Switch to creative mode.
Step 3: Approach the inactive wooden pressure plate.
Step 3: Stand on or fly through the inactive wooden pressure plate.
A large number of wooden pressure plates will drop, the amount will be large enough to crash the game.

A similar issue may affect the new varieties of wooden pressure plate in the upcoming release. I have not observed the problem with the active pressure plate.
