Description Stéphane Magnenat 2020-10-19 14:56:38 UTC

Application: krunner (5.18.5)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-51-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I just pressed F2 to show krunner, and typed thunderbird

- Custom settings of the application:
I just upgraded Kubuntu from 18.04 to 20.04. Krunner did crashed from times to times in 18.04, but not always as it seems to be the case now.

The crash can be reproduced every time.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 1 Alexander Lohnau 2020-10-19 15:03:31 UTC

Are you using Nvidia?

And does disabling plugins help? (Maybe try to disable all an then disable them one by one back).

Comment 2 Stéphane Magnenat 2020-10-19 15:19:40 UTC

Yes, I'm using NVidia, from lspci:

NVIDIA Corporation TU106 [GeForce RTX 2060 SUPER] (rev a1)

From glxinfo:

OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce RTX 2060 SUPER/PCIe/SSE2
OpenGL core profile version string: 4.6.0 NVIDIA 450.80.02

With all plugins disabled, I do not get a crash, but after I type "thunderbird", I a have an infinite progress circle. If I add back just "applications", it works. I will need to add them one by one indeed, I cannot do that now but I'll try later.

Comment 3 Alexander Lohnau 2020-10-19 16:13:44 UTC

The spinner is unrelated and has been fixed a few framework versions ago. And thank you for trying this out :)

Comment 4 Alexander Lohnau 2020-10-30 07:56:13 UTC

Can you please try to install the debug symbols? That might give a better hint where the crash happens.

Comment 5 Stéphane Magnenat 2020-10-30 08:00:38 UTC

I did not find a debug symbol package for plasma-workspace which contains krunner on Kubuntu 20.04. Is there an easy way to recompile a version of the package with debug symbols?

Comment 6 Alexander Lohnau 2020-10-30 08:04:48 UTC

On KDE-Neon:
sudo apt install libkf5runner5-dbgsym plasma-workspace-dbg milou-dbgsym
