I‘ve just disabled the PIM Contacts Search plugin but KRunner is still crashing on my side. I‘ve tried yesterday with only the Applications plugin enabled. This worked fine. 

After that, I enabled one plugin after another and tried again. I do had the cruel behavior that re enabling the plugins didn‘t have an effect. E.g. after enabling the web shortcuts plugin I wasn‘t able to trigger a web search as usual. 

After log out and log in again, I have again the problem that KRunner is crashing all the time.
