Code location: https://github.com/libyui/libyui-qt-pkg/blob/master/src/YQPkgPatternList.cc#L479 So it looks like after the recent changes to use theme icons the error handling leaves to be desired. We should add proper error handling and a proper fallback cascade very much like we do in other places, e.g. in YQUI::loadIcon(): https://github.com/libyui/libyui-qt/blob/master/src/YQUI.cc#L695 Or maybe simply use that (relatively new) YQUI icon loading mechanism.
