EPiServer custom property settings and blowing up the database

So property settings was added to PTB 2.0, and i decided to play around a bit with it and not just change the tinymce settings due to that being boring as ****. When doing so i stumbled across a.. can we say interesting "feature" of EPiServer.

What you normally do is create a settings class that inherits EPiServer.Core.PropertySettings.PropertySettingsBase (or implement the interface)...
