--- Comment #45 from David Edmundson  ---
We've made a report upstream with a reproducible case

We've also ported the two instances that we know of in Plasma code to avoid
doing the quirky behaviour that caused the crash

Potentially there might be other cases inside Plasma. If you get this crash (or
are marked as a duplicate of this) after 5.10.5 please reset this status to
"reopened" with as much information as possible.

Plasma 5.10.5 resolved this issue for me, it does not crash anymore (Bug

[Notifications] Clean up States

While I'm usually a huge fan of States, this is done only half-way with States
in the compact
representation (NotificationIcon) overwriting the plasmoid's state in addition
to there being
a binding on it in main.qml.

It also used a "default" state (note: the default state in QML is empty string)
in addition to
assigning default values on items themselves anyway.

This seems to shift evaluation of bindings into an order where we first stop
the BusyIndicator
and then become passive, moving the the systray popup, working around the Qt
crash we're seeing.

It's a nice clean up in any case imho.

Don't change fillMode of image just before deleting it

It is still set for when a source is applied for the next
transistion.

Summary:
This saves evaluating a new paintedSize and doing a bunch of evaluations
which are not used.

More importantly it works round a Qt animation crash.

fadeAnim.running is bound to otherImage.status !== loading

with the intention of delaying animations until the images are really
loaded.

By setting the fill mode and then the source, we go to loading and back,
effectively restarting the animation from within the animation.
This leads to a crash.

Test Plan:
End user result is the same.

I'm able to reproduce the System Tray crash.

Here are the steps I used:
1. Create a Test folder
2. Add 115 MB .iso file to Test folder
3. Right-click Test folder > Compress > Here (as TAR.GZ)
4. Click Notifications in System Tray while file is compressing
5. Click show details button in Notifications while file is compressing
6. Crash

Do you need a valgrind or backtrace for this one?

That leaves one (that we know of) in file transfers/systemtray.

This happens: 
 - when the notification dialog is open
 - the dialog gets closed because there are no items

If I do "notify-send -t 0 asdasf" (so that the notification applet is still
'active' and doesn't close) it doesn't crash.

Assuming it's the same cause as the other one, it means we're toggling an
animation from inside the animation mid way through it running.

The animation causing the crash is 

BusyIndicatorStyle {
RotationAnimator on rotation {
running: control.running && control.visible && control.opacity > 0;
}

change that to true and it doesn't crash. Remove any one of those components it
still crashes.

Also, RotationAnimator.running is private API of the style so it can't be
influenced externally.

It seems the trigger is completely unrelated to the wallpaper one.
and this one is a lot harder to reproduce in a test case.

Wallapper all fixed and in review.

Killer line is

fadeAnim.running = Qt.binding(function() {

return currentImage.status !== Image.Loading && otherImage.status !==
Image.Loading
})

the idea being to delay the loading until both things are loaded.

But scriptAnimation at the end does:

otherImage.fillMode = fillMode;
otherImage.source = "";

which means from inside the animation we change fillMode - running goes to
false as it reloads the image with the new fillMode (asynchronously)
then we unset the source, running goes to true as it's no longer loading

I think I maybe see something interesting.

SequentialAnimation {
id: fadeAnim
ParallelAnimation {
OpacityAnimator {
}
OpacityAnimator {
id: fadeOtherAnimator
}
}
ScriptAction {
}


we also have

// only cross-fade if the new image could be smaller than the old one
fadeOtherAnimator.enabled = Qt.binding(function() {
return currentImage.paintedWidth < otherImage.paintedWidth ||
currentImage.paintedHeight < otherImage.paintedHeight
})

// Alleviate stuttering by waiting with the fade animation until the
image is loaded (or failed to)
fadeAnim.running = Qt.binding(function() {
return currentImage.status !== Image.Loading && otherImage.status
!== Image.Loading


paintedWidth will be changed after the image has loaded, so we're starting an
animation, then immediately disabling one of the animations within the group of
a running animation.

I'm able to reproduce this crash. 

KDE Plasma Version 5.10.4
KDE Frameworks Version 5.36.0
Qt Version 5.9.1

I've attached the output from: QML_ANIMATION_TICK_DUMP=1 plasmashell and
valgrind --log-file=valgrind_plasmashell --leak-check=full
--show-leak-kinds=all plasmashell

Crash reproduced by doing the following:
1. Right-click on desktop > Configure Desktop
2. Switch positioning from: Scaled, Keep Proportions to Scaled and Cropped
3. Select new wallpaper, click Apply

If anyone can reproduce this in valgrind, that would be really useful.

Also running QML_ANIMATION_TICK_DUMP=1 plasmashell and having the command line
output of the crash would help.
