Description Karel Volný 2015-08-18 08:40:14 UTC

Description of problem:
I've just started 'konsole' via krunner ang got DrKonqi right after that ...

Version-Release number of selected component (if applicable):
plasma-workspace-5.3.2-2.fc22.x86_64

How reproducible:
(don't know)

Steps to Reproduce:
1. hit alt+f2, write program name, hit enter quickly
(I guess the speed is important here, the suggestions did not completely load, but I could be completely mistaken as I haven't managed to reproduce this ...)

Actual results:
Application: krunner (krunner), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
