Description Cezar Tigaret 2020-01-25 09:45:03 UTC
Application: plasmashell (5.17.90)

Qt Version: 5.14.0
Frameworks Version: 5.66.0
Operating System: Linux 4.12.14-lp151.28.36-default x86_64
Windowing system: X11
Distribution: "openSUSE Leap 15.1"

-- Information about the crash:
- What I was doing when the application crashed:
I had updated my KDE and Qt5 libraries as recommended by online update ("Software Updates applet"). 

Since then, Plasma keeps crashing right at startup, either after log-out/log-in or after reboot and log-in.

- Custom settings of the application:

KDE Plasma Version 5.17.90
KDE Frameworks Version 5.66.0
Qt Version: 5.14.0
Kernel Version: 4.12.14-lp151.28.36-default
OS type 64 bit

Desktop customizations:
1. top screen edge panel, always shown, with (left-right): Application Launcher, Window Application Menu (NOT Global Application Menu), System Tray, Configure Displays, Present Windows Button, Wastebin, Digital Clock 
2. left screen edge panel (vertical, auto-hide) with various other applets including a few folder views and icon launchers
3. bottom screen edge: Latte panel with latte dock, System Load applet and Desktop Pager

I use two monitors, and six virtual screens.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

NOTE the same thing happens on my laptop (Samsung Notebook 9), after library update via online update (Software Updates applet). Both machines have the same OS, KDE/frameworks/Qt versions, and desktop configurations.
Comment 2 Cezar Tigaret 2020-01-25 10:17:18 UTC
Other KDE components seem to work except for Dolphin (Bug 416734) that also became unusable after the update mentioned here.
Comment 3 Harri 2020-01-25 10:30:28 UTC
same issue here. 
- What I was doing when the application crashed:
login into plasma session
- Unusual behavior I noticed:
dolphin crashes when starting
dolphin also crashes when starting in xfce session

I tried to send a bug report but: "Der Fehlerbericht kann nicht gesendet werden: /[113] Sorry, but you are not allowed to (un)mark comments or attachments as private../" wtf?

I seems that the most recent patches (~ 15 min ago) solved this and a related (dolphin) issue 

Joy!

Many thanks to all the developers who helped fix this!!!

Have a nice weekend!

Kind regards,

Cezar
