That's what I mean by "reproduce script", what crashes is not the client (your
QT
app) but the server side (php), so we need a reproduce script to know how it
crases :)

I already posted the c++ code (Qt) I use to do the post without content type
header. I do not know a second way to do a similar post.
One can use a empty php file to post to, even than it will crash:
<?php
?>
But the lines i use to read the raw post data:
<?php
//load raw post
$data = file_get_contents("php://input");
//(current dir is writable)
$handle = fopen("./file.jpg", "w");
fwrite($handle, $data);
fclose($handle);
?>

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Test script:
---------------
Qt source for posting binary without content type set:
QString filename = QFileDialog::getOpenFileName(this);
QFile* f = new QFile(filename);
f->open(QFile::ReadOnly);
QNetworkAccessManager* manager = new QNetworkAccessManager(this);
QNetworkRequest req(QUrl("http://www.server.com/post.php";));
// uncomment line below for bypassing error
// req.setHeader(QNetworkRequest::ContentTypeHeader,"image/jpeg");
QNetworkReply* rep = manager->post(req,f);
f->setParent(rep);
