           Summary: Krunner crash when typing first letter or clicking
                    setting button
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general

Application: kcmshell5 (5.7.0)

Qt Version: 5.7.0
Frameworks Version: 5.23.0
Operating System: Linux 4.6.3-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:

Krunner crash every time I type the first letter in the search box. Disabling
plugins is not possible because clicking on the setting button in krunner make
it crash too. It happens every time.

- Custom settings of the application:

I have calculator plugin activated. I've seen it in the backtrace of the
crashing thread so I thought it might be related.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Segmentation fault
