Description SiMH 2015-11-12 10:28:50 UTC

Application: krunner (0.1)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-18-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
Starting KDE. Started happening after upgrade to Kubuntu 15.10
- Unusual behavior I noticed:
After upgrade KDE runs much slower, very unresponsive. I often have to wait a couple of seconds after some actions.

The crash can be reproduced every time.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault

I do *not* experience the problem at log-in (Kubuntu 15.10) but I experience (probably) the same problem from time to time, e.g. sometimes when pressing Alt-F2:
