+Subject: [PATCH] daemon: Infer session type from desktop file if user has no
+ saved session type
+
+The accountsservice user cache file can specify a session type
+associated with the saved session.  This is optional though. If one
+isn't specified GDM needs to figure out the session type based on the
+list of preferred session types for the system and the session file
+itself.
+
+It was failing to do the latter, though.  This commit fixes that.
