Description Kanedias 2018-01-12 18:35:30 UTC 
Application: plasma-discover (5.11.5)

Qt Version: 5.10.0
Frameworks Version: 5.41.0
Operating System: Linux 4.14.13-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:

Open Discover, hit "Applications' -> "Games" in the drawer,
then select anything, 0 A.D. or Steam or whatever so it shows this app page.

Then start typing in the filter field in the drawer, erasing and typing again.
Unfocus, focus again, delete text, type some more, repeat.

After 2-3 attempts you'll get this crash.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Центр приложений Discover (plasma-discover), signal: Segmentation fault
