Junior Job - option to choose between 'WLAN Interface' and 'wlan0' in UI

Hi,

Sorry, I had no internet connection because Vodafone TR's systems had
serious damage with the flood disaster in İstanbul, as I use gprs/3g to
connect. So I just able to look at this.

I have some problem here;

WiredWidget::WiredWidget(Knm::Connection * connection, QWidget * parent)
: SettingWidget(connection, parent), d(new WiredWidget::Private)
{
    d->ui.setupUi(this);
    d->setting = static_cast<Knm::WiredSetting
*>(connection->setting(Knm::Setting::Wired));
    d->ui.mtu->setSuffix(ki18np(" byte", " bytes"));
    foreach (Solid::Control::NetworkInterface * iface,
Solid::Control::NetworkManager::networkInterfaces()) {
        if (iface->type() == Solid::Control::NetworkInterface::Ieee8023) {
            Solid::Device * dev = new Solid::Device(iface->uni());
            QString deviceText;

KNetworkManagerServicePrefs::instance(Knm::ConnectionPersistence::NETWORKMANAGEMENT_RCFILE);

            if (!KNetworkManagerServicePrefs::self()->useTechnicalNames()) {

#if KDE_IS_VERSION(4,3,60)
                deviceText = dev->description();
#else
                deviceText = dev->product();
#endif
            } else {
                Solid::Control::NetworkInterface * iface =
Solid::Control::NetworkManager::findNetworkInterface(iface->uni());
                if (iface) {
                    deviceText = iface->interfaceName();
                }
            }

            Solid::Control::WiredNetworkInterface * wired =
static_cast<Solid::Control::WiredNetworkInterface*>(iface);
            d->ui.cmbMacAddress->addItem(i18nc("@item:inlist Solid Device
Name (kernel interface name)", "%1 (%2)", deviceText,
wired->interfaceName()), wired->hardwareAddress().toLatin1());
        }
    }
}



It crashes with this line: Solid::Control::NetworkInterface * iface =
Solid::Control::NetworkManager::findNetworkInterface(iface->uni());

here is backtrace:

Any clue that why Solid crashs?
