QNetworkRequest add an 'Accept-Encoding' raw header

On linux version only (Mac OSX and Windows versions are ok)

When using the well known QNetworkAccessManager class for download a foo.tar.gz file from a web site, I got this file in my local dir, but in fact the content of the local file foo.tar.gz is foo.tar ! The file seems to be downloaded then unziped then written in foo.tar.gz

The same download with foo.zip or what so ever file works well...

In fact the following code :

         QNetworkRequest req = QNetworkRequest(QUrl(newFilePathToDownload));
         downloadReply_ = netManager_.get(req);

act as this one

         QNetworkRequest req = QNetworkRequest(QUrl(newFilePathToDownload));
         req.setRawHeader("Accept-Encoding","gzip");
         downloadReply_ = netManager_.get(req);

You can reproduce this bug by compiling/taking the Qt examples network/download and type the following command under ubuntu 10.10

./download http://twilmot.free.fr/tt_0_41_linux.tar.gz

the result local wrong file will be as describe upper
