Attachments: New crash information added by DrKonqi

Description info 2020-01-10 19:34:31 UTC 
Application: kate (19.12.0)

Qt Version: 5.13.1
Frameworks Version: 5.65.0
Operating System: Linux 5.3.12-2-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I read about the LSP Client, went to Kate's Settings to search for the plugin and enabled it.
I enabled the plugin by checking the corresponding checkbox.
I saw that something at the bottom of Kate's window changed, so I toggled the checkbox twice more to see what it was.

When I then pressed OK to close the settings dialog, Kate crashed.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

I can not reproduce this, could you try out Kate 20.04?
Thanks!
Comment 2 info 2020-06-22 16:23:54 UTC 
I wasn't able to reproduce it with 20.04, but the bug was not reproducible for me, with the other version either.
