> Please provide a backtrace of the crash.

its attached, under Observed result. Please check it out. A repudouce is a little complicated, because its happend only on my Computer and system
Comment 3 Christoph Feck 2019-07-01 09:49:54 UTC 
Comment #0 does not show the backtrace, but only the Konsole output. Please read https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Re-assigning to print-manager. Got a backtrace sent, looks like plasmashell quits normally?

Very curious. Any idea how to debug this further?

>Very curious. Any idea how to debug this further?

probably hit an assert, put a break on exit
Comment 6 Kai Uwe Broulik 2019-07-04 09:38:28 UTC 
but there's nothing printed on console that suggests an assert
Comment 7 Christian Pubanz 2019-07-06 22:52:27 UTC 
I dont know why, but the bug is fixed. I ve print something and the task bar is running. Its verry courius... 

Thank you for the solution whatever -and a specical thanks go to Kai-Uwe!
