The good news: This seems to fix a long-standing problem I have with<br>
QtWebEngine cookies not being saved on exit:<br>

<br>
The bad news: You seem to be right. I only did a couple of quick tests on<br>
Linux, and so far I got:<br>
<br>
- An abort() due to an error in PyQtSlotProxy::unislot():<br>

(I don't have the error message I'm afraid)<br>
<br>
- An X error and assertion failure inside Chromium:<br>
