Comment 1 elizabeth m. 2020-04-16 09:56:15 UTC 
Hi Ancoron, thank you for your report,

I just tried to reproduce the bug with the steps you outlined, but I didn't experience a crash.

I am running:

Operating System: openSUSE Tumbleweed
KDE Plasma Version: 5.18.4
KDE Frameworks Version: 5.68.0
Qt Version: 5.14.1
Kernel Version: 5.6.0-1-default
OS Type: 64-bit

Kate: Version 20.03.90
Kate Part: Version 5.68.0

I tried it with an empty JSON file and then again with a JSON file with this content:
"{\"name\":\"John\",\"age\":31,\"city\":\"New York\"}"

Is there anything else you noticed that causes the crash, (e.g. does it only happen with a complex JSON file?) and if so can you give me any pointers so I can try again? Are you using any configuration settings that would affect it?

Thank you for your time
