Description NIk 2022-02-10 23:48:34 UTC
Application: plasmashell (5.24.0)

Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.16.5-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.24.0 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I had my VM up and running, but this very error happened before too, even without doing anything. The only program open was Firefox then, and the second time (this report) virt-manager. 5.24 seems a bit .. unstable.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

primaryoutputwatcher.cpp:127 says:
setPrimaryOutputName(qGuiApp->primaryScreen()->name());

primaryoutputwatcher.cpp:72 says:
Q_EMIT primaryOutputNameChanged(oldOutputName, newOutputName);

primaryoutputwatcher.cpp:136 says:
const auto screens = qGuiApp->screens();


So we're crashing trying to get a list of all screens? Could it be empty?

Dont ask me :)
All those complicated lines in my report came from the automatic reporting utility under KDE, I just sent the report and dont know what any of that means.  It happened today again.

Edit: This (https://bugs.kde.org/show_bug.cgi?id=450062) is actually related. Just read the summary part.
Its reproducible. 

When I do this ...:

(Quote)
- Main monitor connected to iGPU via HDMI, same monitor connected to GTX 1660S via DVI (GTX is bound to vfio-pci but shouldnt matter for this)
- When starting a VM, the "2nd monitor" aka GTX @ DVI gets effectively disconnected from the host. When coming back to Plasma after shutting down the VM, all my desktop icons (default folder view) get reset the the top of the screen. Happens 100% of the time and only under wayland

.. Plasmashell crashes. Minus the part that the icons get reset, because that happens only under Wayland, as stated under 
Bug 450062, not X.

Very likely in my case, where the crash always happens (i.e. really every time) when the screen (there's only one) wakes up from stand-by. Syslog shows me stuff like that:

A bunch of messages from kscreen saying that the screen has been disconnected, e.g.
> kscreen_backend_launcher[19076]: kscreen.xcb.helper:         Connection:  "Disconnected"
Several of these, 6x with screen -1 and a lot with screen 0:
> plasmashell[929]: requesting unexisting screen -1
> plasmashell[929]: requesting unexisting screen 0
Then again kscreen reports about the disconnected screen and within a second notices that it has been connected again.
After that plasmashell restarts.

After updating to KDE 5.24.2 on openSUSE Tumbleweed snapshot 20220227 I would carefully say that the issue has been resolved. I tested multiple times to start my VMs, restarted 3 times, tried the same again, plasmashell did not crash this time. 
I just wonder why there is no "solved" or merge request thingy in here, or does that appear later? The other duplicates are also still open.

You can mark the bug as "RESOLVED WORKSFORME".

The "duplicate" bug filed in https://bugs.kde.org/show_bug.cgi?id=450607 has not been fixed in Tumbleweed 20220227.

I'm not saying that "WORKSFORSOME" is not correct in the sense that one possible trigger of the underlying bug may have been fixed. But I fear that setting the status to "WORKSFORSOME" reduces the priority even further.

Given the fact that a core component of the DE is frequently crashing in everyday usage this might send the wrong signal.

I must chime in and say that the frequent crashing for various 
unpredictable reasons not just this particular bug, that was more easily 
reproducible, has force me to abandon KDE and Plasma. I am using OpenBox 
and XFCE and as yet have not had this DM crash once. If this is 
obtainable in this environment, I fear there is and underlying issue yet 
to be tracked down, and setting the status to something that will place 
the issue further on the back burner will only mean the core trigger is 
never found let alone be resolved.

Can you file different bug reports about the other issues?

I agree, changed back to reported if thats correct. I assumed that since its actually fixed for me, consistently, it also is fixed for anyone else but they just didnt report back.

The plasmashell crash when the screen wakes up from energy saving mode doesn't seem to happen anymore in 5.24.3.

Are you able to reproduce this issue in Plasma 5.25 or later?

I no longer use KDE or Plasma. For that matter I no longer use openSUSE. 
I have switch to a much more stable Fedora currently version 36, and use 
XFCE as a DM, and my base memory usage is 3.18 GiB with Firefox and 
Thunderbird loaded as apposed to over 8 GiB with Plasma 5

The latest qt5-declarative has reverted the backport commit from Qt6, so it's expected the bug is not fixed in Qt5.

I believe so, yeah.

Plasma 6 is in progress, so I think at this point we'll have to be okay with it being a Plasma-6-only fix.
