Qt - Writing a file with QTextStream adds empty new lines to the text

I'm using the following code to write some text to a file:

QFile caFile(outputFolder + "file.extension");
caFile.open(QIODevice::WriteOnly | QIODevice::Text);

if(!caFile.isOpen()){
    qDebug() << "- Error, unable to open" << "outputFilename" << "for output";
}
QTextStream outStream(&caFile);
outStream << "First Line\nSecond Line\nThird Line";
caFile.close();

It's working like a charm, but with a little problem .. The text file should look like this:

First Line
Second Line
Third Line

But instead, it looks like this:

First Line

Second Line

Third Line

What's the problem here?

It works for me like a charm.
