Comment 1 Nicolas Fella 2020-10-25 18:51:28 UTC 
I put in a qDebug() << event in dialog.cpp:1350. This is the resulting output right before the crash

QEvent(UpdateRequest, 0x7ffe3e716f40)
QEvent(UpdateRequest, 0x7ffe3e716f40)
QEvent(UpdateRequest, 0x7ffe3e716f40)
QEvent(UpdateRequest, 0x7ffe3e716f40)
QEvent(DeferredDelete, 0x55d045806070)
Object 0x55d04571f5d0 destroyed while one of its QML signal handlers is in progress.
Most likely the object was deleted synchronously (use QObject::deleteLater() instead), or the application is running a nested event loop.
This behavior is NOT supported!

Comment 2 David Edmundson 2020-10-25 23:30:57 UTC 
Can't reproduce:

>#61 0x00007f52ec8e14e7 in operator()(Plasma::Types::ItemStatus) const (__closure=0x55f2ac36af90, status=Plasma::Types::ActiveStatus) at /home/nico/kde/src/plasma-workspace/applets/systemtray/systemtraymodel.cpp:205

This could be quite telling. Why would this be in the trace if it's just the notification itself closing
Comment 3 David Edmundson 2020-10-25 23:33:44 UTC 
and what is this doing:

#19 0x00007f52f612ba87 in QQuickLoader::setSource(QUrl const&, bool) (this=0x55f2ad9f5090, url=..., needsClear=<optimized out>) at items/qquickloader.cpp:426


I think we're setting our status to inactive, and that's triggering some loader in the system tray popup view, that deletes whatever used to be loaded by the same loader.

And something in that first loader is what triggered this event hence the warning.
Comment 4 David Edmundson 2020-10-27 15:49:37 UTC 
And with respect to the assert

#18 0x00007f52f3cc9071 in QCoreApplicationPrivate::sendPostedEvents(QObject*, int, QThreadData*) (receiver=0x0, event_type=52, data=0x55f2aa576210) at kernel/qcoreapplication.cpp:1817

after we setSource we flush the event queue, which is akin to the nested event loop.
Good news is that it's probably the system tray changes and therefore master only.
Comment 5 Leszek Lesner 2020-10-27 23:27:23 UTC 
I can confirm the issue. Here is my log: https://pastebin.com/xLqT1jeM
Comment 6 Volker Krause 2020-10-28 09:59:40 UTC 
Seeing this here too, recent master and Qt 5.15 branch, seems to happen when the notification popup content is automatically emptied or something like that, not unconditionally on every closed notification.

As a workaround it seems to help here to let a few notifications pile up in DND mode, and then continue normally.
Comment 7 David Edmundson 2020-10-30 00:10:49 UTC 
>As a workaround it seems to help here to let a few notifications pile up in DND mode, and then continue normally.

Makes sense as it'll be the notification applet changing status that is triggering this.

Do you have steps on notifications/setup that can trigger this?
Ideally with notify-send
Comment 8 David Edmundson 2020-10-30 00:37:52 UTC 
As a fix, I think we can set asynchronous: false in systemtray's ItemLoader

Possibly even port to DelegateChooser

I'll need someone who can reliably reproduce to test that.
Comment 9 Leszek Lesner 2020-10-30 01:30:20 UTC 
I can constantly reproduce it by using kdeconnect and sending a ping message from my phone to laptop. If I don't touch the message after the timeout of the message ran out it crashes plasma. 
If I touch the message and halt the timer with my mouse and then let it run again by hovering over something else. I don't see the issue.
Comment 10 David Edmundson 2020-10-30 11:16:05 UTC 
@leszek thanks, I can get the state changing when I send a notification. Still no crash though.

@volker can I have your trace.

There's a bit of the backtrace that I can't match up, I'm hoping if your Qt is self-built it might have a bit more.

Comment 13 David Edmundson 2020-10-30 21:09:31 UTC 
Nicoclas shared this on PM:

>https://codereview.qt-project.org/c/qt/qtdeclarative/+/319750 sounds relevant


Which could explain why I don't see it, I have latest Qt 5.15 branch.
Volker also said he he latest 5.15 branch, but he could be a liar. Backtrace implies that.
Comment 14 Volker Krause 2020-10-30 21:48:11 UTC 
Of course I didn't have that patch yet, my backtrace is from 12:28 UTC, that change only finished integration at 12:56 UTC and I need a non-negative amount of time to build it :D

I'll test that tomorrow. If that's indeed the fix, note that this is currently only in 5.15(.3) and not the 5.15.2 branch yet it seems.
Comment 15 Leszek Lesner 2020-10-30 22:26:48 UTC 
Tested the linked patch for Qt 5.15 (https://codereview.qt-project.org/c/qt/qtdeclarative/+/319750)

Only applying this to my 5.15.2 base and rerun my kdeconnect ping test showed this really fixed the issue. 
So it is an upstream issue apparently that has been fixed and hopefully will land in 5.15.2 before the release.
Comment 16 Volker Krause 2020-10-31 06:12:18 UTC 
Seems to hold up here as well.
Comment 17 Nicolas Fella 2020-11-01 17:39:27 UTC 
Can confirm this is fixed
