Using keyring on Linux leaves dbus-daemons running, perhaps because godbus connection is not closed

My app does not use "secret-service" backend on Linux, however each execution leaves dbus-daemon running, which eventually leads to OutOfMemory.
godbus.Conn has both Open() and Close(), however keyring does not have a Close() method, so there is no way to request Close() in godbus.Conn. I'm not 100% sure Close() will help, but it seems godbus does a lot of clean up in this method.
