+Subject: [PATCH 7/8] Fix SIGSEGV on disconnections
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Sometime, at start of the system, dbus-daemon was crashing
+because a pending authorisation were reactivating a closed
+connection.
+
+Also, clean unused function.
