Description andy86 2019-11-22 14:31:33 UTC

Application: plasmashell (5.17.3)

Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 5.3.12-arch1-1 x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I'm Opening (left click on) Application Menu.

Occasionally it occurs randomly in other situations apparently without logical connection.


- Unusual behavior I noticed:
Crash and restart.


I try to delete ~/.local/share/kactivitymanagerd/resources/, crash is still happening.

The crash can be reproduced sometimes.

-- Backtrace:

Comment 1 Nate Graham 2019-11-22 18:22:10 UTC

Crashing in the NVIDIA driver. Nothing we can do about this, I'm afraid. Please report it upstream to NVIDIA. Thanks!

Comment 2 andy86 2019-11-30 17:46:18 UTC

New crash. This time the nvidia driver is not mentioned in backtrace.
