+Subject: [PATCH] Do not reset widget palettes on changing style
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Generally, resetting a widget's palette from outside its code is a bad practice because the palette may have been changed for a reason.
+
+If the custom palette of a widget needs an update when the style changes, the program itself is responsible for that; otherwise, the program has a bug — as in libfm-qt's places view (which I'll fix soon) and Dolphin's main view (which will never be fixed).
