When the St theme is changed, the StThemeContext unrefs all the theme nodes cached in it's internal hash table, then emits a signal to notify all theme nodes that the current theme has changed. The problem is that the first StWidget to catch a theme changed signal will trigger a "style-changed" signal catched by its children first. So the theme changed signal can't be processed properly to cleanup StThemeNodePaintState before recomputing the theme. This patch adds a weak ref to the StThemeNode in the StThemeNodePaintState to ensure paint states are properly cleaned up when the associated StThemeNode is freed. https://bugzilla.gnome.org/show_bug.cgi?id=703859
