Description Peter Kreussel 2016-12-03 09:50:11 UTC

Application: plasmashell (5.8.4)

Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.8.11-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
What I was doing when the application crashed:
- returning from hibernate (that's what the backtrace belongs to)
- or from suspend
Plasma crashes and restarts. Not every time, about every 6th or 7th resume from powersave mode or so.

The crash can be reproduced sometimes.

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

I am also observing this behaviour.
Coincidentally, I'm also using a NVidia graphics card on a 64-bit system:

OpenGL vendor string: NVIDIA Corporation                                                                                      
OpenGL renderer string: GeForce GT 520/PCIe/SSE2                                                                              
OpenGL core profile version string: 4.5.0 NVIDIA 367.57                                                                       
OpenGL core profile shading language version string: 4.50 NVIDIA                                                              
OpenGL core profile context flags: (none)                                                                                     
OpenGL core profile profile mask: core profile

This crashes inside the nvidia proprietary driver. There's not much we can do, sorry.
