Guard against all exceptions

[san650]

The idea is to use this addon to manage low priority user configurations, this means that it's preferable to lose a configuration value than to raise an exception to the user.

The idea is to catch any exception and log the warning to the console. A nice to have is to change the adapter to memory adapter when an error occurs and store the configuration there. The problem with this approach is that you can potentially lose previous configurations on the current session.
