+Subject: [PATCH] gdbus: Avoid printing null strings
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This mostly affects the 2.56 branch, but, given that GCC 9 is being
+stricter about passing null string pointers to printf-like functions, it
+might make sense to proactively fix such calls.
+
+gdbusauth.c: In function '_g_dbus_auth_run_server':
+gdbusauth.c:1302:11: error: '%s' directive argument is null
+[-Werror=format-overflow=]
+ 1302 |           debug_print ("SERVER: WaitingForBegin, read '%s'",
+ line);
+       |

+gdbusmessage.c: In function ‘g_dbus_message_to_blob’:
+gdbusmessage.c:2730:30: error: ‘%s’ directive argument is null [-Werror=format-overflow=]
+ 2730 |       tupled_signature_str = g_strdup_printf ("(%s)", signature_str);
