I see, thanks for explanations.

What about to refactor UMLFileDialog::currentMimeFilter() to something like 
/**
 * @brief return the mime type of the currenty selected file
 * @return mime type string
 */
QString UMLFileDialog::currentMimeFilter()
{
    KUrl url = m_dialog->selectedUrl();
    QFileInfo fi(url.toLocalFile());
    return UMLViewImageExporterModel::imageTypeToMimeType(fi.suffix());
}

which is already the default case on windows ?
