+Subject: [PATCH] file monitor: Fix invalid read
+
+Commit 7373acf changed file monitor construction to be really
+synchronous. Unfortunately there is missing g_object_ref for d-bus
+connection and the connection is unrefed after use. Subsequent read
+of the unrefed connection cause crash with following critical:
+
+(firefox:29844): GLib-GIO-CRITICAL **: g_dbus_connection_is_closed:
+assertion 'G_IS_DBUS_CONNECTION (connection)' failed
+
+Do not store the connection, because it isn't neccesary with the
+synchronous construction.
