Description cybea 2018-09-06 11:54:34 UTC 
Application: konsole (18.08.0)

Qt Version: 5.11.1
Frameworks Version: 5.49.0
Operating System: Linux 4.15.0-33-generic x86_64
Distribution: KDE neon User Edition 5.13

-- Information about the crash:
- What I was doing when the application crashed:

select or paste text in vim

(usually I work with vim and select or paste text while pressing shift key due to changed vim behavior automatically switching to visual mode when not pessing shift key)

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault

Comment 1 cybea 2018-09-06 12:02:07 UTC 
additional notes:
- this happens since ~1 Month ago. I always keep my system uptodate. (kde-neon user edition)
- I always work with multiple konsole windows and tabs
- this bug is really annoying and makes work with konsole a pain

New crash information added by DrKonqi

konsole (18.08.1) using Qt 5.11.1

- What I was doing when the application crashed:

Starting a block selection using Ctrl+Shift+Alt (instead of just Ctrl+Alt) while the prompt was off-screen (i.e. scrolled some way up). I cannot always reproduce the crash, but I can say that it is unrelated to vim. Started to experience that crash a few weeks ago.

introduced by fcea6742c142fdbfdf53d17c862bfae7652fae3b, I think, that removed a check where it crashes.

reverting that should fix it.

Comment 13 cybea 2018-11-08 23:29:07 UTC 
Why does this bugfix doesn't get "backported" to 18.08?
To me it seems like a trivial patch for an annoying crash.

What I did to get my assumption:
  $ git clone git://anongit.kde.org/konsole
  $ cd konsole
  $ git branch -r --contains 5006d0e194d642d8059e15edf9704fd38b579979

It's back again.
Comment 18 Martin Sandsmark 2020-09-06 11:56:02 UTC 
Consistent way to reproduce:

1: Generate enough scrollback to scroll up
2: Scroll up and select something
3: Start something that uses the alternate screen buffer (e. g. vim)
4: Hold down shift and press the mouse button (to start a new selection)

Fix

This fixes it here by invalidating the selection in TerminalDisplay when switching Screen.

I'm not sure why they duplicate the beginning of the selection, but this is the simplest solution at least.

New crash information added by DrKonqi

konsole (22.08.0) using Qt 5.15.5

I won't be able to reproduce this consistently, but I just had Konsole 22.08 crash with a similar stack trace while selecting text with the Shift key pressed.

Can you tell what was the terminal size when the crash occured? Specifically, how many lines it had?(In reply to Ilya Bizyaev from comment #23)

Can you tell what was the terminal size when the crash happened? Specifically, what was the terminal height?
Were you using a full terminal application (like vi), or in command line?

I believe the terminal height was 45 lines. I was using VIM on a remote
host via ssh session.
