QXmlQuery::evaluateTo(QString) adds a line break

[mentalmushroom]

I noticed that QXmlQuery always adds an extra line break to the returned value (when evaluating to QString)

QXmlQuery q;
q.setQuery("'aaa'");
if (q.isValid() && q.evaluateTo(&s))
{
		s.append("b");
		qDebug()<<s<<endl;
}

QXmlQuery q;
q.setQuery("'aaa'");
if (q.isValid() && q.evaluateTo(&s))
{
		s.append("b");
		qDebug()<<s<<endl;
}

To copy to clipboard, switch view to plain text mode 

The code above produces strange output:

"aaa
b"

"aaa
b"

To copy to clipboard, switch view to plain text mode 

instead of expected "aaab".

Is that a bug or am I doing something wrong?
