Description Matt Fagnani 2024-06-05 14:15:13 UTC

SUMMARY

I was using Plasma 6.0.90 on Wayland in Fedora Rawhide QEMU/KVM VMs in GNOME Boxes using the llvmpipe driver in a Fedora 40 host. plasmashell sometimes crashed in SystemClipboard::checkClipData::ClipboardMode after copying and pasting files in nautilus. https://bugs.kde.org/show_bug.cgi?id=488023 I've seen such crashes twice out of several times doing so. Two drkonqi windows appeared which showed "Gathering the crash information failed for unknown reasons. You can retry or close the windows." at the top. Clicking See Developer information showed "The crash information couldn't be generated" in the middle. The drkonqi windows had messages at the bottom "You need to first install the debugger (gdb) then click the Reload button" even though gdb was installed. Clicking Retry didn't change anything. This problem only seemed to happen with the first crash which showed drkonqi in a VM. Subsequent crashes only showed one drkonqi window and showed traces without the errors above. I reproduced the crash by running and aborting kwrite in Konsole with
kwrite &
pkill -6 kwrite

STEPS TO REPRODUCE
1. Boot a Fedora 40 KDE Plasma installation updated to 2024-6-4 with updates-testing enabled
2. Log in to Plasma 6.0.5 on Wayland
3. Start Konsole
4. Install GNOME Boxes if it isn't already with sudo dnf install gnome-boxes
5. Download Fedora-KDE-Live-x86_64-Rawhide-20240604.n.0.iso from https://koji.fedoraproject.org/koji/buildinfo?buildID=2460858
6. Start GNOME Boxes
7. Boot Fedora-KDE-Live-x86_64-Rawhide-20240604.n.0.iso in a GNOME Boxes QEMU/KVM VM with 4.0 GiB RAM, UEFI enabled, and 3D acceleration disabled using the llvmpipe mesa driver with a shared folder in the host
8. Start Konsole
9. kwrite &
10. pkill -6 kwrite

OBSERVED RESULT
Two drkonqi windows appeared with errors for the first crash in Plasma 6.0.90 VMs

EXPECTED RESULT
One drkonqi window should've appeared without errors.

SOFTWARE/OS VERSIONS

journal for boot when two drkonqi windows were shown for the first kwrite crash

The journal at the time of the first kwrite crash showed two drkonqi services start drkonqi-coredump-launcher@0-2031-1000.service and drkonqi-coredump-launcher@1-3698-0.service. Then there were errors like drkonqi[3712]: org.kde.drkonqi: "Failed to seek to cursor: (22) Invalid argument" polkit-kde-authentication-agent-1 crashed. org.kde.drkonqi.saveCoreToFile failed to authorize through polkitd. drkonqi-polkit-helper was not authorized. drkonqi failed to excavate core as admin with QDBusError("org.freedesktop.DBus.Error.AccessDenied", ""). There were SELinux denials of various daemons including polkitd and pkla-check-authorization connecting to /run/systemd/io.systemd.NamespaceResource, but the drkonqi problem happened with previous Fedora Rawhide images in which those denials didn't happen. I'm attaching the journal from which the following is the most relevant part.

Comment 2 Harald Sitter 2024-06-05 23:48:08 UTC

The STEPS TO REPRODUCE do not yield the described result for me. Can you check again please?

Comment 3 Matt Fagnani 2024-06-06 00:24:23 UTC

I've tried the steps with running and aborting kwrite as the first crash in the boot about 10 times, and I found that the problem happened about 50% of the time. There might be a race condition. There were also two drkonqi notification icons in the System Tray when it happened. Sometimes the drkonqi windows weren't always automatically shown and I had to click on Report Bug in the notification or click on the drkonqi icons in the Tray. Thanks.

Comment 4 Matt Fagnani 2024-06-10 05:38:05 UTC

The polkit-kde-authentication-agent-1 crash in comment 1 didn't create a core dump. I ran sudo gdb -p $(pidof polkit-kde-authentication-agent-1) to attach gdb to polkit-kde-authentication-agent-1 in Plasma 6.0.90 on bare metal. I ran and aborted kwrite. Two drkonqi icons appeared in the System Tray, and when I clicked on them and Report Bug in their notifications, they showed the errors I reported. polkit-kde-authentication-agent-1 crashed in g_source_destroy with what might've been an invalid pointer source=0xaaaaaaaaaaaaaaaa

On different boots, there were two drkonqi icons for the first crash, but there weren't the errors in drkonqi I reported. drkonqi could create the traces correctly at those times. When there weren't errors in drkonqi, polkit-kde-authentication-agent-1 didn't seem to crash.

This report is about two drkonqi windows appearing sometimes for the first crash of plasmashell or kwrite while bug 489096 is about plasmashell crashing in SystemClipboard::checkClipData. The crashes in SystemClipboard::checkClipData I reported at https://bugs.kde.org/show_bug.cgi?id=488023 were more like bug 489096.

Comment 7 postix 2024-07-16 10:56:52 UTC

I see, I'll un-dup and reopen it again. :)
