What happens?
kulala.nvim has a UI window which can be closed once done with it. Each time I close it, I get the above stack trace and the tabufline breaks completely.

I am closing the window using the plugin's built-in keymap 'q', so it is not like I am closing this window in any improper way.

Neovim version:

NVIM v0.11.0-dev-1684+g0c8890e7a7
Build type: RelWithDebInfo
LuaJIT 2.1.1736781742

I disabled noice.nvim just to eliminate it from the picture. Here is the new stack trace:

i will test it tomorrow 👍

[daniel-odrinski]

Thank you very much 🙂

vim.api.nvim_create_autocmd("BufAdd" , {
  callback = function(args)
    vim.print{args.buf, vim.bo[args.buf].ft}
  end,
})

@mistweaverco do you use eventignore for your plugin? i dont see it at bufdelete event, weird

[glmlm]

Here is the new stack trace:

@daniel-odrinski Could you please update the ui plugin to the latest version and try the same thing again?
I have recently fixed a similar issue(#442), so so it is possible that the problem has already been resolved.

[siduck]

@glmlm its not related to that

{
    "mistweaverco/kulala.nvim",
    lazy = false,
    opts = {},
  }

and then run

:lua require("kulala").open()

and go to that window, press q

[daniel-odrinski]

@glmlm Can confirm that your fix does not fix this issue.

[glmlm]

@siduck @daniel-odrinski It appears that the issue is due to the buffer number nr of kulala.nvim being left in the vim.t.bufs. I'm investigating the cause little by little, but I'm afraid I cannot help you at the moment.

[daniel-odrinski]

Thank you so much for your help @glmlm @siduck

[glmlm]

@daniel-odrinski Could you please test my PR? This might solve the issue.

@siduck If you wouldn't mind confirming that this implementation is correct, I would be very grateful. I must admit that I have not read all of the code, so I am not sure if this is appropriate.

[daniel-odrinski]

Will do @glmlm thanks :)

i know, the bufdelete even handler must remove it but idk how it ignores

[daniel-odrinski]

@glmlm @siduck I am happy to report that this fix works :) Thank you so much!

[siduck]

dont close yet, i'll come back to this issue in few weeks and merge the code to main branch
