      The following code segfaults as a result of the `qDebug`:

      #include <QtCore/QDebug>
#include <QtCore/QVariantHash>
#include <list>

int main(int, char**)
{
  std::list<int> sdl;
  auto containerVariant = QVariant::fromValue(sdl);
  QVariantHash vh;
  vh.insert(QStringLiteral("container"), containerVariant);
  QVariant varppp;
  varppp = vh.value(QStringLiteral("container"));
  qDebug() << varppp;
  return 0;
}

      It also segfaults when the `qDebug` is removed, due to the `QVariant` destructor.
