Sentry Crash Report:

Description Peter Kreussel 2017-01-04 14:32:24 UTC 
Application: krunner (5.8.5)

Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.8.13-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
--opening Krunner with Alt+Space
--typing "kwr"
--selecting result "KWrite", pressing Enter

I am using Nvidia 375.26. 
This has been happening for quite a while (= different versions of plasma-framwork on Arch Linux). Not very often, but Krunner does not restart, which makes this a bit of a bother.

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