[BUG]: Opening trouble with diagnostics breaks

[Diaoul]

Requirements

• [X] I have skimmed other issues to see if this bug has already been reported.
• [X] I'm fully certain that this is not a breaking change, see the latest release.
• [X] This plugin and its dependencies are up to date with the latest commit.
• [ ] I'm willing to fix this through a PR.

Expected Behavior

When I open diagnostics with trouble I have no error message.

Actual Behavior

   Error  21:26:15 msg_show.lua_error Error executing vim.schedule lua callback: ...cal/share/nvim/lazy/barbecue.nvim/lua/barbecue/theme.lua:172: table index is nil

Minimal Configuration

That's a good question, I tried using default lazyvim as starting point but I could not reproduce despite having similar configuration.

• I have tried disabling attach_navic but it does not do anything
• I also have Trouble as ignored filetype but it does not seem to do anything and as soon as I open trouble the message shows exclude_filetypes = { "netrw", "toggleterm", "Trouble" },
• I also have verified that the filetype is actually "Trouble" and it is

The only thing that prevents the issue is disabling autocmd with create_autocmd = false.

Reproduction

Still working on a minimal setup.

• My dots are here
• Clone into ~/.config/diaoul_nvim
• NVIM_APPNAME=diaoul_nvim nvim
• Press <space>xx to trigger the issue

Seems to be coming from this part of my config:

  {
    "nvim-tree/nvim-web-devicons",
    lazy = true,
    opts = {
      override = {
        default_icon = {
          icon = "",
        },
      },
      color_icons = true,
    },
  },

Fixed with https://github.com/Diaoul/dotfiles/commit/164ee82f3a7cb2254ef00826da6e9111bbc2fa15

Maybe that's something to look into still, seems weird that it makes barbecue.nvim crash where no other plugin do.
