monitoring
Product: ksysguard
Version: 5.17.4
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: dark...@nearce.com
Target Milestone: ---

-- Information about the crash:
- What I was doing when the application crashed:
This crash occurs on close of ksysguard. It happens somewhat sporadically, and
I believe it may be related to long running KSysGuard processes. Possibly
related to watching graphs.
The crash can be reproduced sometimes.
-- Backtrace:
Application: System Monitor (ksysguard), signal: Segmentation fault
