ADDITIONAL INFORMATION

I know this is very much an edge case but figured I would report it anyway. I am reporting this under konsole as this is where I experienced the corruption but I assume this could happen to any app.

A random garbage program filled my /home and, I assume, konsole went to overwrite the previous existing ~/.config/konsolerc and failed in writing the full file, effectively losing all settings. 

I can't think of a real solution to this, only thing I could imagine was if /home was <1M then don't write the config. A warning popped up once it was at 0% full and offered to open filelight which was a nice touch.
