Port names are not correctly null terminated contain garbage symbols

[GoogleCodeExporter]

What steps will reproduce the problem?
1.I use Qt 4.7.2 with minGW 4.4 / Eclipse integration
2.Use QextSerialEnumerator::getPorts()
3.read portName member of returned struct

What is the expected output? What do you see instead?
Should read "COM1", "COM2" ... Instead of this I read QString object, long 10 
characters, null terminated at the middle, which contains illegal symbols (code 
from near memory addresses)

What version of the product are you using? On what operating system?
Qt 4.7.2, mingw 4.4, QextSerialPort-1.2win
OS: WinXP
Exe code produced from mingw, produces same effect on different machines.

Please provide any additional information below.
Sample code:

        portList = QextSerialEnumerator::getPorts();    
    for(it=0;it<portList.size();it++)
    {       
        qDebug() << portList.at(it).portName;
        qDebug() << portList.at(it).portName.size();
        qDebug() << portList.at(it).portName.toAscii().toHex();
    }

Output of this:

"COM1
10 
"434f4d3100223f220303" 
"COM2
10 
"434f4d3200003f3f0303" 

On next execution there are differences:

"COM1
10 
"434f4d31003f033f0403" 
"COM2
10 
"434f4d32003f3f3f0203"
