Bug 509630

SUMMARY
We have a bash session running a python programm (roslaunch) that starts our robot control software. It produces lots of output so we/some of my coworkers set the history to 1.000.000 lines. Now after 2-5 hours konsole just disappears.

STEPS TO REPRODUCE
1. start konsole
2. roslaunch ...
3. wait a few hours

OBSERVED RESULT
log files indicate "KeyboardInterrupt" being send to python, konsole cleanly exits, logs say:

Sep 17 17:41:17 mikado-20016 systemd[1535]: app-org.kde.konsole-8b2980e9dd78468ea40c8aaff7ec0612.scope: Consumed 1d 2h 18min 22.845s CPU time.

ADDITIONAL INFORMATION
We do not observe this behavior with the same setup and gnome-terminal (running for 12h+ now)

We have coredumps activated but none are being written, looks like a clean exit
