Resetting the settings doesn't work correctly:

- even though I didn't change the theme, clicking the "Set settings to default values" button changes the window titlebar theme to Adwaita (but I was using Ambiance). This happens even without saving the changes.
- some settings aren't restored: I've disabled Global Menu and Overlay scrollbars and clicking "Set settings to default values" doesn't reset them. There might be other settings that aren't resetted too...

Here's the output I get when selecting to set settings to their default values:
Traceback (most recent call last):
