[Qt-interest] Memory usage in QXMLQuery

[Aeon]

hi.
i'm trying to use QXmlQuery in my application, but have strange problem:
it seems that QXmlQuery  allocate memory for every query but never 
release it.
Fedora 12, Qt 4.5.3, 4.6.0

QXmlQuery query;
QString query_result;
foreach(QString tmp, filenames)
{

   QFile file(tmp);
   if (!file.open(QFile::ReadOnly))
     {
       qDebug() << "cant open file";
       break;
     }

   query.bindVariable("inputDocument", &file);
   query.setQuery(queryString);

   if (query.isValid())
     {
       query.evaluateTo(&query_result);
     }
}

i've found thread with similiar problem in archive (July 2008, "Memory 
use in QXMLQuery in Qt4.4 under Windows")
one and a half years passed, Qt 4.5, 4.6...  still no solution?
