+Subject: [PATCH] src/nbd: initialize info_headers to NULL
+
+When g_variant_dict_lookup() does not find the given key, it does not
+modify the values of the arguments provided.
+
+This results in info_headers being undefined and can cause the
+rauc-nbd-server to crash, which will result in a broken request on
+client side that lets RAUC terminate hard with:
+
+(rauc:769): rauc-nbd-ERROR **: 15:40:30.553: failed to recv nbd config reply header
+
+The behavior of g_variant_dict_lookup() has also recently been clarified
+in the glib documentation:
+https://gitlab.gnome.org/GNOME/glib/-/merge_requests/3334
+
+Upstream-Status: Submitted [https://github.com/rauc/rauc/pull/1332]
