Application: ksysguard (5.17.4) Qt Version: 5.13.2 Frameworks Version: 5.65.0 Operating System: Linux 5.0.0-37-generic x86_64 Distribution: KDE neon User Edition 5.17 -- 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 Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
