Description Pascal Vanier 2012-05-19 09:12:47 UTC

KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.3.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I selected a big portion of text and cut it (Shift + V, Shift + D), this does not happen when cutting a small portion of text (a few lines) only with really big ones.

- Custom settings of the application:
vi input mode

The crash can be reproduced every time.

-- Backtrace:
Application: Kile (kile), signal: Segmentation fault

Forwarding to KatePart.
Comment 2 Dominik Haumann 2012-05-21 06:32:12 UTC 
I thought this was fixed in KDE 4.8.3?

Pascal, can you please install debug infos and test again to provide a better backtrace?
Even better is if you quickly build Kate from sources by following http://kate-editor.org/get-it/

Possible duplicate of #292947
Comment 3 Pascal Vanier 2012-05-21 17:36:43 UTC 
It only happens in kile, for the moment it never happened in kate : but I use kile heavily, while I only use kate on small files (I just tried to make kate bug and did not manage to, but kile didn't either right now). I'm building kate and kile from sources, and I'll use them and see if they crash.

kate (3.8.3) on KDE Platform 4.8.3 (4.8.3) using Qt 4.8.1

- What I was doing when the application crashed:
Same as before, cutting text in a file	
- Custom settings of the application:
Still in VI mode, maybe I should add that it was while working on a .tex file, I doubt the tex file is relevant as it happened to me in several of them.

Comment 5 Pascal Vanier 2012-05-21 18:23:58 UTC 
I forgot to add that this is with a compiled from sources kate, maybe I can improve the bug report (as it does not seem to add information to the previous one), but I don't know how (I'm on arch, there does not seem to be a debug symbols package).

kate (3.8.3) on KDE Platform 4.8.3 (4.8.3) using Qt 4.8.1

- What I was doing when the application crashed:
Copy pasting, it seems it is related to copying the last line of the file. I already managed to make it crash without this condition, but it is always the case with it.

- Custom settings of the application:
Vi input mode, the source file is not relevant, tried with .tex and other files
I compiled kate from git
