QSslSocket::defaultCiphers() causes lockup if called before creating an instance of QSslSocket

Example code, works (prints out more than "pre") after removing comments:

#include <QCoreApplication>
#include <QSslCipher>
#include <QSslSocket>
#include <QDebug>

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);

// QSslSocket *socket = new QSslSocket();
// socket->deleteLater();

qDebug() << "pre";
qDebug() << QSslSocket::defaultCiphers();
qDebug() << "post";

return a.exec();
}
