Gzip html files shows weird chars in chrome - google-chrome

Question

using gzip on my php output like this
if( isset($compression['html']) && $compression['html'] == TRUE)
{
ob_start("ob_gzhandler");
header("cache-control: must-revalidate");
header("expires: ".gmdate('D, d M Y H:i:s', time() + $compression['expire'])." GMT");
}
produces the error show in the image below. It works fine in FF and Safari, but in chrome it does not. Any idea how to solve it?
This is the header I get
