[Qt-interest] QDomElement::setAttribute problem

[matteo]

I have the following code:

QDomElement PositionPartElement = 
XmlDocument.createElement("positionElement");
float d0;
d0 = 2001;

PositionPartElement.setAttribute("d0",d0);
....
....
....

FatherElement.appendChild(PositionPartElement);

The result must be:
   <partElement>
    <positionElement x="314.67" y="1752.95" z="439.655" d0="2001" />
...
...


If I use the QtXmld4.dll (debug) it runs.
If I use QtXml4.dll (release) it prints:
   <partElement>
    <positionElement x="314.67" y="1752.95" z="439.655" d0="2000.:" />
...
...

It's a bug?

Thanks
Teo
