Operating System: Linux 4.15.0-51-generic x86_64
Distribution: Ubuntu 18.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was trying a simple mathematic statement, like =2.56*546 (or similar). As I can see this involve the embedded KCalc functionality. Sometimes 'krunner' crashes. The current is just an example.

The crash can be reproduced sometimes.

Is this still reproducible on newer versions?
Comment 2 Здравко Гърмев 2020-10-14 13:15:35 UTC 
To be honest I don't use this feature since. I just tried and seems everything works fine, but this isn't guarantee. Crashes got brought up from time to time, in the past rather often. Even more, from time to time krunner's addon module disappeared even without math expressions inside. A good news is that recently krunner seems more stable and doesn't crashed since some time at all. In this context we can assume some upstream release has fixed the issue, even not confirmed unconditionally.
Anyway... We can set this case closed. If the same brings up again, I will post again here or open new bug report.
Thanks for your interest, Alexander Lohnau!
