Operating System: Linux 4.7.0-rc7+ x86_64

-- Information about the crash:
when I used alt-F2 to start konsole after logging into a plasma desktop, krunner crashed and konsole started alright, except for failing to display unicode characters correctly.

The crash can be reproduced sometimes.

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