Comment 1 Friedrich W. H. Kossebau 2021-09-16 05:52:04 UTC 
Thanks for the report. Cannot reproduce here with with current Okteta & Konsole as of openSUSE TW packages (Konsole 21.08.1, Okteta 0.26.6) though. And seems a bug rather in Konsole by the backtrace, at least I think Okteta code is not interfering with anything related to where the crash happens, cmp. also https://invent.kde.org/utilities/okteta/-/blob/0.26/libs/kasten/controllers/document/terminal/terminalview.cpp

Sidenote: you might want to poke the Fedora maintainer of the Okteta package to update to more receent 0.26.6 (released 2021-03-29) over what seems current with Fedora (0.26.4 from 2020-07-28).

There was a similar bug on Dolphin and konsole, it was fixed in konsole a
few days ago.

Comment 3 Jan Paul Batrina 2021-09-16 10:02:27 UTC 
I also think this is https://bugs.kde.org/show_bug.cgi?id=441206, and the fix was backported to stable and released in 21.08.1
Comment 4 Ahmad Samir 2021-09-16 11:07:07 UTC 
Indeed, a duplicate of bug 441206.
