+Subject: [PATCH] ascli_refresh_cache: fix NULL pointer dereference
+
+The command `appstreamcli refresh-cache --cachepath /tmp/cache`
+segfaults. In this code path, `ret` (initialized to `FALSE`) is not
+updated when `as_pool_load` returns successfully and sets the `error`
+pointer to NULL. Then the code tries to print `error->message`.
