Maybe fixed the bug in Qt then. But doing this kind of hit-and-run patching, blindly trying to workaround a bug is really bad as it greatly increases the maintenance cost.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Could you please ensure that no threads are involved? Add stuff like Q_ASSERT(QThread::currentThread() == thread()) to the dtor of the class.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
If that does not help, then certainly there is a bug elsewhere, maybe inside Qt, and should be fixed there then.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">And Qt removes pending events from the event queue when an object is deleted. <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">Only</em> when threads are involved there might be race conditions.
