ku: Invalid shaders/program/notch.json: null

I discovered a new snapshot was released and figured to go and play with it.
While poking around in the settings (because I had reset my instance and needed to change the display/audio settings for my system), I noticed this NPE in my logs (I keep the launcher open):

It did this when I clicked on "Broadcast Settings".
It ONLY does this when you click on it via: main menu -> options -> broadcast settings, it doesn't do this when you go through the pause menu.
Not exactly sure why it's trying (and failing) to load a shader in the options menu...

I couldn't find this bug on the tracker and figured to report it!
