Application: konsole (16.04.3)

Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.4.0-98-generic-tuxonice x86_64

-- Information about the crash:
Since about ten days - guess after updating system - konsole chrases all the
time after some while, maybe five minutes to some hours.
Even lookink for an reason, I can't see any dependency with user activity.

The crash can be reproduced every time.
