Description Andy3153 2020-01-15 20:36:37 UTC

Application: plasmashell (5.17.5)

Qt Version: 5.14.0
Frameworks Version: 5.66.0
Operating System: Linux 5.4.11-arch1-1 x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Using Plasma normally. I think I switched virtual desktops

- Custom settings of the application:
I have the custom Thermal Monitor and the Application title plugin, both got form built-in widget installer
I use Kvantum, using theme Sweet
I also use glava, if it helps with anything. I keep it open basically non-stop

The crash does not seem to be reproducible.

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

Unfortunately the backtrace does not implicate any KDE code and is missing a lot of debug symbols. It's not debuggable right now, sorry. :( Does it still happen in Plasma 5.21? If so, can you please attach a backtrace with complete symbols? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks!
