I found a workaround from twust (sorry, don’t know how to add the link):
Workaround : in mqtranslate_utils.php use the old function.
function qtrans_parseURL($url) {
/*
TWU : causes bug for absolute URL.
$result = parse_url($url);
if ($result === false) */
return __legacy_qtrans_ParseURL($url);
This did the trick for me! Hopefully this will be fixed in the next release.
