"new QFileDialog" vs. "getSaveFileName" drive names

[Rayven]

I have created an new QFileDialog to get the save filename. However, the drive chooser does not list the drive names just the letters. For instance:
"Local Disk (C" just prints as "C:". This is VERY frustrating when there are multiple networked drives and all I see are W, X, Y and Z printed.

To make matters more confusing if I use the static getSave/OpenFileName calls, the drive names appear correctly.

QString filename = QFileDialog::getSaveFileName( this, tr("Save"), QDir::home( ) );

QString filename = QFileDialog::getSaveFileName( this, tr("Save"), QDir::home( ) );

To copy to clipboard, switch view to plain text mode 

vs

QFileDialog *saveDialog = new QFileDialog( this, tr("Save"), QDir::home( ) );
saveDialog->setAcceptMode( QFileDialog::AcceptSave );
 
if( saveDialog->exec( ) ) ...

QFileDialog *saveDialog = new QFileDialog( this, tr("Save"), QDir::home( ) );
saveDialog->setAcceptMode( QFileDialog::AcceptSave );
 
if( saveDialog->exec( ) ) ...

To copy to clipboard, switch view to plain text mode 

Is there something that I need to set to make the drive letters appear?

Thanks
