I have the terminal plugin enabled but is not opened while reproducing this bug.

OK, maybe not Bug 441206.

Can you reproduce the issue?

Unable to reproduce but a full stacktrace may be more helpful (the top 5 functions are missing...)

Can you maybe try to do the following:
- `gdb kate`
- make it crash
- go back to terminal and type: bt
- copy the backtrace and paste here.

Alternatively, you can try the following as well:
- Run Kate
- Make it crash
- once crashed, run the following command immediately:
 coredumpctl debug

Copy the backtrace here

Yes. If you open Kate, type something, and close Kate without saving the file the mainwindow closes and drkonqi is immediately triggered due to a crash then.

Here is a backtrace from gdb. If I am missing any additional debug symbols kindly let me know. Hope it helps.

@Rahul

Can you please share what plugins you have enabled? (Go to Settings->Configure Kate -> Plugins -> See enabled plugins)

Also, please share if you have the "Replicode Plugin" enabled.

Seems like all the available plugins are enabled. Here is a screenshot -> https://pasteboard.co/CHLOwAGTnoc7.png

And yes, Replicode among all other plugins is also enabled.

Many thanks for the patch, @Wakar. Will wait for it to get shipped to Kubuntu 21.10 packages before I can start using it.

You can disable the Replicode plugin for now and it will not crash.
