+Subject: [PATCH] gdbusnameowning: Downgrade ReleaseName warning on closed
+ connection to debug
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+g_bus_unown_name() calls ReleaseName synchronously after checking that
+the connection is still open. However, the connection can close on the
+worker thread between the check and the call, which commonly happens
+during session shutdown when the bus daemon exits while clients are
+still running cleanup code.
+
+When this race occurs, the ReleaseName call fails with G_IO_ERROR_CLOSED
+and produces a spurious warning in the journal. Downgrade to g_debug
+since the name release is best-effort — the bus daemon is gone, so the
+name is already unowned.
