hang
Product: ksysguard
Version: 5.12.8
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org

-- Information about the crash:
GNU Octave hung when I edited a file which was stopped at a debug breakpoint.
I then closed System Monitor (which had been running since before I started GNU
Octave) which crashed rather than closing normally.
-- Backtrace:
Application: System Monitor (ksysguard), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
