+Subject: [PATCH] Fix konsolepart Segfault when closed
+
+Assign the _view as the parent to the KXMLGuiFactory because the factory
+is referencing the view widget as its associated widget. Since the
+TerminalDisplay gets destructed first this is now a dangling pointer.
+If the view is set as the parent the factory gets cleaned up correctly.
+
+Also cleanup the created clientBuilder after destruction because it
+cant have a parent and would probably leak memory.
