Subject: [PATCH] Fix use-after-free in error message reporting

archive_error_string (a) must be called before archive_read_free (a)
so that _g_error_new_from_archive_error can copy the error string.
Otherwise load_data->error is set to "Fatal error" or gibberish instead of the
proper error message
