Cycled widget styles (such as the battery charging style) were broken until now. The reason for this: They maintain state that represents the current cycle position (i.e. what is the current icon that is being displayed), but that is done in a way that uses repr() on the widget object. Since the widget objects are re-created each time the bar is drawn, this is a deeply flawed design. Instead, use the instance() of the widget for now.
