+- Add unset-xdg-runtime-dir.diff to unset XDG_RUNTIME_DIR in processes
+  run with kdesu. This fixes the problem which made most kde applications
+  (like dolphin or kate) not usable when run as another user with kdesu. 
+  kdesu worked to run those applications as root, but then, sockets
+  were created in / . This patch also fixes the creation of those files
+  which will be created on /tmp/runtime-<username>/ (boo#1009510).
