Plasma-workspace crash after logging since kf5 framework update to 5.31 Dmesg output: 17.825019] ksplashqml[1270]: segfault at 7fffaff98fc0 ip 00007f7f12430a0b sp 00007fffaff98fc0 error 6 in libc-2.24.90.so[7f7f123a9000+1c3000] Rebuilding plasma-workspace and plasma-desktop with the new framework not solves the issue.
Any chance of a full backtrace? Otherwise, on the surface, the immediate crash is happening in glibc
Same issue when rebuilding all plasma packages to 5.9.1. Seem's to be a kf5 framework issue. I will try to downgrade every package one by one to find the problem.

possible too that plasma-5.9 changed how theming/looknfeel works in some non-backward-compatible way.
Downgrading kf5-kpackage and its depencies (kf5-kcoreaddons kf5-ki18n) solves the crash. Plasma starts now,I'll try to find another debugging mode. Thanks for your help.
Found the reason of the crash. A kf5-kpackage upstream patch: From e6d72cb9df6f55b3f463a5acfcad6a7bafe4bd81 Mon Sep 17 00:00:00 2001 From: Aleix Pol <aleixpol@kde.org> Date: Thu, 29 Dec 2016 01:12:23 +0100 Subject: Improve installation process of KPackage bundles When parsing the desktop files, pass together the kpackage-generic.desktop service type, so that the parser knows its intrinsic types (most especially X-KPackage-Dependencies which is in fact added now). This is important because otherwise we get warnings when we extract the value when the package is a desktop file. This would be much less of a problem if desktop service types could be extended, but it's not the case at the moment.

Mind reporting it upstream so they have a chance to fix it?
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.
I have this exact same problem with my Fedora 24 installation, after updating kf5 to version 5.31. Shall I write a new bug or clone this one for Fedora 24?
This issue should be fixed with plasma-5.8.6, f24 builds are: https://bodhi.fedoraproject.org/updates/FEDORA-2017-c262a33752 We can close this one and track upstream, http://bugs.kde.org/376508
