Sorry for reviving this old issue.
I can reproduce this issue every time, even with the newest Kubuntu 20.04 LTS
(In 18 and 19 too). I can't find any threads of bug reports that end with a
proper solution for this issue. I am not an Ubuntu expert, but the errors as
seen below and the issues described in bug seems very similar, so I assume it
is related?

I'm not sure why this marked as resolved fixed, since in Fedora 23, running
plasma 5.6.5, it's still very reproducible.   I verified that the SRPM for
Fedora 23's latest updates contain the fix in the commit listed at the top of
this ticket, and my previous bug (marked duplicate, 364613) contains as much
debug information as I could retrieve to state that.

Since  I can very reliably reproduce this bug, what can I do to help fix it?

I'm still getting plasmashell crashes everytime my monitors wake up from
standby. KF 5.21, Plasma 5.6.4, Qt 5.6.0. Plasmashell is usually gone when they
wake up, and my windows have been moved around. I do not get a Dr. Konqui
message box anymore, though, the shell is just simply gone, so I can't post a
trace.

@David can you fill "Version Fixed In" with the actual version ?

This still happens with Qt 5.6.0RC and plasma 5.5.4, will this be fixed in the

Sure. To make sure I removed the Qt patch I mentioned in my earlier bugreport
and to make sure I have your patch, I recompiled the 
kde-plasma/plasma-workspace-5.5.4 package again. Here's the start from the
compile log, where it lists the patches used
(plasma-workspace-5.5.4-crash-fix.patch is your patch):

>>> Emerging (1 of 1) kde-plasma/plasma-workspace-5.5.4::gentoo
 * plasma-workspace-5.5.4.tar.xz SHA256 SHA512 WHIRLPOOL size ;-) ...

>>> Source prepared.

So I think this is covered. I have a new backtrace generated by simply turning
off my main monitor and then turning it back on again, but it is too big to
paste here, so you can find it here: https://paste.kde.org/pcdzif4s7

Your original report was a duplicate, the trace you just uploaded is different
to your original one.

(it's a dupe of the QScreen animation timer one... which is somewhere else,
fixed in newer Qt)

Git commit 5a1a411b41f950e97d80ff7c898052fb6d02fb1a by David Edmundson.
Committed on 03/02/2016 at 17:32.
Pushed by davidedmundson into branch 'master'.

Fix the Plasma::Applet::Actions crash

We were mixing KScreen and QScreen API.

Corona.cpp checks we are requesting a containment for a valid screen
if (screen >= 0 && screen < numScreens()) {

This fails as numScreens() is Qt API based, whereas the signal we're
adding the output for is ShellCorona::addOutput

Edit.
Urgh. It's obviously the latter because that uses the qscreen API rather than
the KScreen API triggering this.

Will fix.

> "m_views" is empty, and thus "m_views.count()" is zero

Well that's right.
That's saying. Get me the contianment for screen 0.

The bigger question is why createContainmentForActivity() returns a null
pointer.

Possible causes:
m_desktopContainments[activity][0] is a valid entry, but null.

containmentForScreen(int, QString, QVariantList) returns a null pointer.

which would happen if defaultPluginIfNonExistent doesn't exist
OR 
we fail this check
if (screen >= 0 && screen < numScreens()) {

I'm experiencing the same issue.

The bug is that in this code
https://quickgit.kde.org/?p=plasma-workspace.git=blob=17ce61b57f71332b9b4029d44301462ef90d3dfd=1f826604749f36e899034d55d02a910e31584f60=shell%2Fshellcorona.cpp

>DesktopView *view = new DesktopView(this, newScreen);
>
>Plasma::Containment *containment = 
> (m_activityController->currentActivity(), m_views.count());
>Q_ASSERT(containment);
>
>QAction *removeAction = 
> containment->actions()->action(QStringLiteral("remove"));

"m_views" is empty, and thus "m_views.count()" is zero. Hence "containment" is
NULL, so dereferencing this pointer triggers the crash.

different external monitor and resuming).
