Patch to work around problem in Akregator

This patch provides a workaround in Akregator for the Qt bug, and it may be
possible to do something similar in Kontact. Not sure whether it should be
incorporated into the master sources, though, as hopefully it will be fixed
upstream.

Did you create a phabricator task for your patch ?

No, because I assumed (from the Qt bugreports) that it had been fixed in 5.9 or
certainly in 5.10.

It still happens with Qt 5.11.2. There are some fresh stack traces in
https://bugs.debian.org/910852.

I'm not certain if the problem I'm experiencing is exactly the same, but for
the last few versions (of both qt5 and akregator), the "preview" flickers and
never shows anything. I see a stream of "org.kde.pim.webengineviewer: WebEngine
render process crashed" messages if I start akregator from a terminal.

Haven't had time to try to custom-build a "debug" installation (Arch Linux, if
that matters).

Oddly, I actually tried downgrading qt5, akregator, kdepim, etc. and have not
been able to find a version that _doesn't_ do this on my system for akregator
any more.

Falkon, on the other hand, still works normally, so I'm assuming this isn't a
problem with qt5 webengine itself.

At one point I'd found a posting on one of the QT websites that (as I recall)
was blaming this on some kind of thread-safety issue in the way
kdepim/akregator was using it, but I can't find the page any more and may be
mis-remembering.

Not sure if that helps, but figured I'd throw in what information I have.

Possible duplicate (or similar, anyway) bugs 399299 and 401638.

This patch provides a workaround in Akregator for the Qt bug, and it may be

I'm experiencing this bug on Gentoo and can confirm that the proposed patch
fixes the problem.
