Description Alex 2018-03-11 00:13:56 UTC

Application: plasmashell (5.12.1)

Qt Version: 5.10.1
Frameworks Version: 5.43.0
Operating System: Linux 4.15.3-2-ARCH x86_64
Distribution: "Arch Linux"

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

Just searched word 'sys' in menu. Any other word of such length also reproduce the bug

- Unusual behavior I noticed:

Whole thing is crashes, sometimes it's just pannels, sometimes desktop disappears too and only windows are left(i.e. kwin).

I use Arch Linux and installed whole Plasma through meta-packages following Arch Wiki instructions.

The crash can be reproduced every time.

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