Description Giuseppe Calà 2016-08-28 14:56:14 UTC 
Application: krunner (5.7.4)

Qt Version: 5.7.0
Frameworks Version: 5.25.0

Krunner 5.7.4 is starting crash very often, but I found a way to make it crash everytime: tring to calculate an operation with / and *, for example 15/5*3, 28/4*9, etc

it shows the result for a couple of seconds and then it crashes. 

Reproducible: Always

Steps to Reproduce:
1. activate krunner
2. try to evaluate 15/5*3

Actual Results:  
result shown for a couple of seconds then it crashes

Expected Results:  
just show the result

-- Backtrace:
