+Subject: [PATCH] Cancel the GDBusObjectManager operation to fix a potential
+ crash
+
+If blues takes longer than 1500ms to successfully start, then we will call
+fu_bluez_backend_connect_cb() with a freed FuBluezBackendHelper.
+
+Hopefully fixes https://bugzilla.redhat.com/show_bug.cgi?id=1949491
