QSystemTrayIcon segfault on MacOSX if you hide() while in slot connected to activated()

Hello,

When you try to hide() a QSystemTrayIcon while responding to its activated() signal, Qt segfaults on MacOSX.
It also segfaults on ubuntu if you do a right click on the tray icon. I was able to fix the problem on ubuntu by using Qt::QueuedConnection for the connect() call, and on MacOSX my workaroud was to use QTimer::singleShot(1000, m_tray_icon, SLOT(hide())).

Here's some code that should help you understand the problem:

configurator::configurator(QWidget *parent) : QMainWindow(parent)
{
m_tray_icon = new QSystemTrayIcon(QIcon(":/icons/logo.png"), this);
connect(m_tray_icon, SIGNAL(activated(QSystemTrayIcon::ActivationReason)), this, SLOT(tray_icon_clicked()));
}

void configurator::hideEvent(QHideEvent* event)
{
hide();
m_tray_icon->show();
QWidget::hideEvent(event);
}

void configurator::tray_icon_clicked()
{
showNormal();
m_tray_icon->hide(); // segfaults!
}
