You need to disable weather information in screensaver settings.
It should work fine then.

I have it disabled already since the beginning when I start using your screensaver: Enable weather information checkbox is not enabled.
With that setting previous version of your screensaver was working properly.

What I did is: I have installed Weather add-on and enabled Weather Information in screensaver - now it works.
But anyway its easy to reproduce: uncheck Weather Information in screensaver while no Weather addon is installed and you get the error.

I'll figure this out and fix it, thank you for letting me know.
