[articleviewerwebengine] Reinstate crash "workaround" for Qt 5.13

It seems that this code is still needed, without it Akregator crashes
again here when opening/closing tabs.

Uses SetUrlRequestInterceptor() on 5.13+ instead, as
SetRequestInterceptor() is deprecated.

Scratch that.

I used page()->SetUrlRequestInterceptor() before (as in
https://cgit.kde.org/akregator.git/commit/?h=Applications/19.04=ead2a27ecbbdf8a6aa83bde13d8a7114f7af7876)
and it still crashed.

But profile->SetUrlRequestInterceptor() instead seems to work fine.

--- Comment #55 from Wolfgang Bauer  ---
Removing the QtWebEngine version check (i.e. reactivating the "workaround" for
Qt 5.13 and higher too) does indeed seem to fix the crashes here.

That causes this warning though (with Qt 5.13):
Use of deprecated not thread-safe setter, use setUrlRequestInterceptor instead.

Unfortunately, if I change it to use SetUrlRequestInterceptor() instead, it
still crashes... :-/

> qt 5.13.0
Indeed, I can confirm the crashes are back with that Qt version.

The "problem" seems to be that the "workaround" to avoid the crashes is
disabled for Qt 5.13 and higher (also done in
https://cgit.kde.org/akregator.git/commit/?id=1ccd68157a1309a2b11f3cece420bb2df6da2e02),
but apparently it would still be needed.

You can try akregator from here:

Git commit cfb973c74fece37d5b52e10dda011c3c9c1be86a by Wolfgang Bauer.
Committed on 21/05/2019 at 16:14.
Pushed by wbauer into branch 'Applications/19.04'.

Fix crashes with Qt 5.12

Commit 1ccd6815 moved the creation of the mNetworkAccessManager down
without a mentioned reason, but that apparently causes crashes with Qt
5.12 at least.

Moving it back to the top seems to fix that.

To be more precise, moving the "mNetworkAccessManager = new

seems to fix it.

Well, this is KDE's bugzilla.
But yes, I suppose I'll submit the revert to KDE:Applications until this is
fixed upstream.

[kontact] [Bug 371511] kontact/akregator crashes while trying to open a link from the list (middle click)

--- Comment #26 from András Manţia  ---
Do you see a crash of aKregator as well? From your description it seems that is
something else, not what was fixed. If you have a debug build (or you can
install the debug symbols on Arch), try to run akregator in gdb and provide a
backtrace.
Still I think this is a different problem and should be reported in a separate
report.

--- Comment #25 from S Clark  ---
Well, either it's not fixed or the problem I've had for the last few months is
different (see comment #10). I've just updated to "Akregator 5.10.1"
(akregator-18.12.1 package in Arch Linux), but for me it's still busted.

Previews just plain don't work on akregator for me - the preview pane flickers
incessantly leaving a blank white panel. If I start akregator from the console,
each flicker results in a message on terminal saying
"org.kde.pim.webengineviewer: WebEngine render process crashed", so I get a
steady stream of those until I close akregator.

Falkon continues to work fine, which seems to indicate it's not QT WebEngine
that's broken.

Anything specific I can check? Is this the same issue reported here, or should
I open a new issue?

Theoretically anything related to opening and closing webpages in Akregator is
a duplicate in the sense that even if the exact reproducing method is not the
same, the patch should fix it. 
 I just found out though, that there are other webengine instances, outside of
Akregator in Kontact, so probably not all kontact crashes (eg. Kontact crash on
close) are fixed by it.

--- Comment #10 from S Clark  ---
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.

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.
