Frameworks Version: 5.50.0
Operating System: Linux 4.17.17-1 x86_64
Distribution: "KaOS"

-- Information about the crash:
- What I was doing when the application crashed:
I was closing a markdown document which is part of a git repository by clicking the tab bar close buton.
Randomly, but reproducible very often; a document close cause the preview panel to crash the application.

The crash can be reproduced every time.

IIUC, the backtrace isn't complete, you need to at least install the debug package for kate.

Comment 4 Filipe Azevedo 2018-11-27 20:02:19 UTC

The issue is still present and i can now reliably reproduce it:

- Have a tree of markdown files in a hierarchy of folders
- Have the root folder be a git repository
- open this repository as a project in kate
- open multiple files from the project panel
- activate the preview panel
- click on each document in the top tab bar (please note that i enabled the top tabbar in plus to the document panel)
- when the last tab bar entry on the right is active, close it from its close button
- crash

Comment 5 Filipe Azevedo 2019-02-17 14:49:53 UTC

up ?

Comment 6 Christoph Feck 2019-03-09 00:05:22 UTC

Please add a backtrace with debug symbols.

Adding ktexteditorpreviewplugin mainter for inspection.
