Menu Crash / Freeze

Sometimes, not always

when entering settings menu

after clicking any element

my game freezes then disconnects and starts infinite loading

I've had the same problem in 0.4 and today it got worse. I just had four crashes when opening the Options menu. First, it crashed immediately after scrolling. Second it crashed immediately after opening. Third it crashed immediately after clicking the field for background FPS. Fourth it crashed immediately after entering one digit into the background FPS field.
