Bug 414845

Application: ksysguard (5.17.0)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-24-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed: I closed ksysguard from the latte panel (hover over running program, press close on thumbnail)

- Unusual behavior I noticed: i was attempting to run solaris-qt Version v2.8.1.0-1a02f8e at the same time, yet was getting errors that Solaris was running and could not open, so I verified with ksysguard that it was in fact NOT RUNNING before attempting to start solaris-qt again

-- Backtrace:
Application: System Monitor (ksysguard), signal: Segmentation fault
