LUA errors when entering dungeons

[sprort]

WoW Version 9.0.2 (37176) (Release x64)

Upon entering dungeons (only tested with Halls of Atonement, Plaguefall, Mists of Tirna Scithe, and The Stockade) LUA errors appear and the chat frames become unresponsive. They appear to be related to the Substitutions module, but disabling that module doesn't seem to fix the issue. As of right now the addon cannot be used when inside a dungeon at all. Due to the sheer amount of LUA errors and the frozen chat frames.

What locale are you? I have Substitutions enabled and it works just fine.
