+    kcms/lookandfeel: Guard for QGuiApplication before using styles
+    
+    LookandFeelManager is invoked from QCoreApplcation startplasma. This
+    must remain a QCoreApplication as it starts up kwin_wayland.
+    
+    This newly added safety check in lookandfeelmanager meant we loaded the
+    style. Use of QGui libraries in a QCoreApplication is undefined or
+    worse.
+    
+    startplasma should only call us with a hardcoded default.
