Bug 2129479

I'm guessing this and https://bugzilla.redhat.com/show_bug.cgi?id=2133795 are likely the same. Is it OK with you if we close this as a dupe of that? This report is earlier, but that one has a full backtrace. Thanks!

The trace was a generic Qt abort one so the errors from the journal were likely more informative and specific than the trace. https://bugzilla.redhat.com/show_bug.cgi?id=2133795 didn't explain that the crash started with Qt 5.15.6 and happened only when xdg-desktop-portal-kde was run by sddm. If you think it's better to mark this report as a duplicate of that one, that's fine with me. I don't recall being asked before a report of mine was marked as a duplicate before :) xdg-desktop-portal-kde crashed in the same way with Plasma 5.26.0 in Fedora-KDE-Live-x86_64-Rawhide-20221010.n.0.iso and earlier when I disabled autologin from sddm in System Settings and logged out to sddm.

FEDORA-2022-239ba8f359 has been submitted as an update to Fedora 37. https://bodhi.fedoraproject.org/updates/FEDORA-2022-239ba8f359

I updated to sddm-0.19.0^git20221025.fc24321-1.fc37 from koji in Plasma 5.26.1 in a F37 KDE Plasma installation. xdg-desktop-portal-kde crashed when run by sddm during each of three boots with sddm-0.19.0^git20221025.fc24321-1.fc37 with the same trace and errors in the journal as I reported. The commit "disable automatic portal launching" at https://github.com/sddm/sddm/commit/fc24321541f6f65b7d1aac89cd82336ffd53e1a0 looks like it's intended to fix this problem, but it might not be sufficient to do so.

Proposed as a Freeze Exception for 37-final by Fedora user ngompa using the blocker tracking app because:

 Fixes crashes for xdg-desktop-portal-kde with KDE Plasma and should go along with Plasma 5.26.

sddm on Wayland (and sddm on X) still crashed with sddm-0.19.0^git20221025.fc24321-1.fc37 each time it started.

Thanks.

xdg-desktop-portal-kde has continued crashing each time sddm on Wayland started since sddm-0.19.0^git20221025.fc24321-1.fc37 was pushed so I'm reopening this report. xdg-desktop-portal-kde crashed twice each time sddm on Wayland started when run by the sddm user 989 with the same errors and traces in my F38 KDE Plasma installation with sddm-0.19.0^git20230306.572b128-1.fc38.x86_64, kwin-5.27.3-1.fc38.x86_64, and qt5-qtbase-5.15.8-6.fc38.x86_64. These crashes were followed by repeated errors like xdg-desktop-portal-gnome[1152]: Failed to initialize display server connection: Unsupported or missing session type ''  as I reported at https://bugzilla.redhat.com/show_bug.cgi?id=2176759 As I mentioned in comment 12, Nicolas Fella wrote "https://invent.kde.org/qt/qt/qtbase/-/commit/725ab072130ca3ce4104f4351e48fe50f57ae330 is needed for the fix to be effective" at https://bugs.kde.org/show_bug.cgi?id=458865#c60 That patch might need to be added to qt5-qtbase to fix this crash.

I updated to sddm-0.19.0^git20230312.d00b2ce-0.fc38.1 from Neal's COPR https://bugzilla.redhat.com/show_bug.cgi?id=2178971#c7 with Aleix's patch https://bugzilla.redhat.com/show_bug.cgi?id=2178971#c6 in my F38 KDE Plasma installation. I rebooted and logged in and out a few times. The xdg-desktop-portal-kde crashes didn't happen on boot. One xdg-desktop-portal-kde crash when run by sddm appeared to have happened when logging out along with crashes of plasmashell, org_kde_powerdevil, drkonqi, and xdg-desktop-portal-kde run by my user. I booted Fedora-KDE-Live-x86_64-38-20230317.n.0.iso in a QEMU/KVM VM with GNOME Boxes and logged out and in 2 times, and the xdg-desktop-portal-kde crashes happened 5 times each when sddm started. I updated to sddm-0.19.0^git20230312.d00b2ce-0.fc38.1 from a VT and ran sudo systemctl restart sddm. I logged in and out of Plasma a few times. xdg-desktop-portal-kde crashes didn't happen when run by sddm. Aleix's patch appears to prevent the xdg-desktop-portal-kde crashes when run by sddm most if not all of the time.
