+Subject: [PATCH] Don't loose xfwm4 when closing session with multiple windows
+ waiting for user input
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When closing a session with more than one window open and waiting for unsaved
+data to be closed, at the next session xfwm4 was not started properly.
+
+The bug(fix) could be reproduced by
+
+* opening gedit
+* entering some text
+* opening terminal
+* closing session (no YNC-dialog / wait ~1min to close session)
+* reopen session
+
+Bugreport with this patch is found at [1] further discussion at [2].
+
+Upstream-Status: Pending
