Crashes from time to time

[masaeedu]

Hello there. Thanks for setting up this nice GUI frontend, I've been missing something like this for a while.

I've been running into issues where gnvim crashes from time to time with a trace like this:

➜  mcpanel git:(master) ✗ RUST_BACKTRACE=1 gnvim

I can't be 100% sure because the crash is really abrupt, but I believe it's happening whenever it tries to open a completion popup.

I don't have any Rust expertise, so I'm not sure what's going on here, but I thought I'd open an issue to report the crash.

[smolck]

Hello! Thanks for opening this issue! Reading the stacktrace it appears that the crash is occurring in the get_icon_pixbuf function. Probably failing at the .unwrap() call here (only call to .unwrap() in the function): https://github.com/vhakulinen/gnvim/blob/65846f45020b338fedd932b058c9e8036dadd976/src/ui/popupmenu/completion_item_widget.rs#L121-L123

Makes sense that this would happen when opening a completion popup, because it's part of what needs to happen when doing that action. What plugin are you using for completion?

Also, what are the outputs of nvim --version and gnvim --version?

[masaeedu]

@smolck Here's the version numbers:

➜  mcpanel git:(master) nvim --version; gnvim --version
NVIM v0.4.3
Build type: Release
LuaJIT 2.1.0-beta3
Compilation:
Compiled by nixbld

Features: +acl +iconv +tui
See ":help feature-compile"

   system vimrc file: "$VIM/sysinit.vim"
  fall-back for $VIM: "

"

Run :checkhealth for more info
gnvim 0.1.5

The plugin I'm using is coc.nvim.

[smolck]

Could you comment out your init.vim and see if the problem still occurs?

Can't seem to reproduce this issue on my machine, but I'm using neovim-nightly. Would you mind also testing this with the latest master of neovim to see if it's an upstream issue with neovim 0.4.3? (I see you're using Nix, so if yes, I can post an overlay I use on NixOS to compile and install neovim master from source if you need/want it.)

[smolck]

@masaeedu Are you still experiencing this issue?

[masaeedu]

@smolck Unfortunately I stopped using gnvim so I can't say. I appreciate your offer to provide an overlay I can test this out with but my current editor set up is held together with duct tape, peanut butter and prayers, and I don't have the time to fix stuff at the moment. Sorry I can't be of more help at the moment.

[smolck]

@masaeedu No problem! If you do start using GNvim again and experience this issue, please don’t hesitate to re-open this issue or create a new one!

Hi, Im experiencing the same issue, also using coc.nvim, When I commented out my whole init.vim file, it didnt happen anymore.

But id like to use coc.nvim, so hopefully this gets fixed.

gnvim 0.1.6 NVIM v0.4.3 I am also using nixos, and installed it with this package: https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/editors/neovim/gnvim/default.nix

(and it seems maybe masaeedu also uses nix, so might be related)

[vhakulinen]

I guess that your system doesn't have required svg related libraries preset. For reference: https://github.com/NixOS/nixpkgs/issues/13537#issuecomment-332327760. I'm not too familiar with nixos, but does that comment ring any bells?
