Description Simone 2017-09-19 10:37:09 UTC

Application: plasma-discover (5.10.5)

Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.12.13-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I open Discover, I type something in the search box, it shows me some results and the spinner "Still looking" at the bottom; then, after few seconds, it crashes. I'm on ArchLinux.

The crash can be reproduced every time.

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