Application: krunner (5.12.1)

Qt Version: 5.9.3
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-32-generic x86_64
Distribution: KDE neon LTS User Edition 5.12

-- Information about the crash:
- What I was doing when the application crashed:
I had a lot of windows open in multiple activities I was using most of my RAM at the time.
- Unusual behavior I noticed:
The KRunner window took a long time to open, and then when I started to type in it, it crashed.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
