Sentry Crash Report:

Description tuxtoriel 2017-03-20 18:52:59 UTC 
Application: kdevelop (5.0.4)

Qt Version: 5.8.0
Frameworks Version: 5.32.0
Operating System: Linux 4.10.1-1-MANJARO x86_64
Distribution: "Manjaro Linux"

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

Editing code. Sometimes, when I hit period, to repeat my last action (I use Vi mode), KDevelop crashes.
It crashes only when the edit command that is being repeated begins with 'o' or 'O'(so «new line & edit above / below» respectively). With 'i','a','I' or 'A', there is no problem, even if in the edit there is a new line added.

- Custom settings of the application:

Vi mode enabled.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

*** Bug 381957 has been marked as a duplicate of this bug. ***
Comment 3 Simon St James 2017-07-04 08:34:05 UTC 
I'm not set up for Kate development at the moment, so could someone do me a favour and test with the calls to

m_viewInternal->repaint ();

removed from commandOpenNewLineOver and commandOpenNewLineUnder? Looks like those were added in prehistoric times and might no longer be needed.

Thanks!
Comment 4 Dominik Haumann 2017-07-11 21:05:36 UTC 
Interestingly, there are quite a lot of repaint() calls... Typically, an update() should have been enough, as far as I understand. In any case, I do not know why these calls were added - maybe because the cursor appearance changes from normal to insert mode and vice versa. I'm currently testing, but not sure I get this done today.
