Did you run PyRoom before another version, perhaps?
Looks like something's wrong with the theme you're using. Deleting ~/.config/pyroom and ~/.local/share/pyroom should restore default settings and make PyRoom work again.
If you did change theme settings in PyRoom preferences or by hand, I'd be interested in what could have changed the problem with that.
If this is a fresh installation that has never been run, the problem would be someplace else and would require further investigation
