Bug 356426

Summary: krunner crashed when system under heavy load
Product: [Plasma] krunner Reporter: Alexey Min <alexey.min>
Component: generalAssignee: Kai Uwe Broulik <kde>
Status: RESOLVED DUPLICATE    
Severity: crash    
Priority: NOR    
Version: 5.4.3   
Target Milestone: ---   
Platform: Gentoo Packages   
OS: Linux   
Latest Commit: Version Fixed In:
Sentry Crash Report:

Description Alexey Min 2015-12-09 13:55:43 UTC 
Qt Version: 5.5.1
Operating System: Linux 4.0.5-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:
opened krunner using a keyboard shortcut, typed in "smplayer" (usually this always works fine)
then the crash happened

- Unusual behavior I noticed:
My system was heavily loaded. Disk was very busy copying lots of files (using dolphin) and VirtualBox was running, compiling updates for virtual Gentoo. CPU was busy up to 98% sometimes


Reproducible: Sometimes




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