Comment (by kanenas):

 It get this notice in debug bar with '''WordPress 4.3.1''', it appears
 randomly on backend. See a couple examples below:

 Dashboard > Home

 {{{
 WARNING: wp-includes/class-http.php:2136 - gzinflate(): data error
 require_once('wp-admin/admin.php'), do_action('admin_init'),
 call_user_func_array, _maybe_update_plugins, wp_update_plugins,
 set_site_transient,
 apply_filters('pre_set_site_transient_update_plugins'),
 call_user_func_array, KM_UpdatesV3->set_update_transient,
 KM_UpdatesV3->_check_updates, KM_UpdatesV3->sendApiRequest,
 wp_remote_post, WP_Http->post, WP_Http->request,
 WP_Http->_dispatch_request, WP_Http_Curl->request,
 WP_Http_Encoding::decompress, gzinflate
 }}}

 Dashboard > Updates

 {{{

 How do I check if gzip decompression is disabled on my server? I am on
 shared hosting environment.
