Failed to open image file with Image Viewer eog

[cgbahk]

Environment

• Operating System: Ubuntu 22.04
• Vim/Neovim version :version:

  NVIM v0.6.1
  Build type: Release
  LuaJIT 2.1.0-beta3
  Compiled by [email protected]
  
  Features: +acl +iconv +tui
  

• NERDTree version, found on first line of quickhelp ?: 6.10.16
• Are you using any of these NERDTree-dependent plugins?
  None of suggested plugins.
• Provide a minimal .vimrc file that will reproduce the issue.
  It's too big... https://github.com/cgbahk/vimrc

Steps to Reproduce the Issue

1. Given image file, say image.svg of image.png
2. Using NerdTree menu feature, browse to the image file in Nerdtree, press m then o to execute the file with system editor

Current Behavior (Include screenshots where appropriate.)

No log, image viewer not opened

Expected Result

Image viewer (eog, https://en.wikipedia.org/wiki/Eye_of_GNOME) opens up to show image.

I recently migrate into nvim. I've used vim in combination with NerdTree for 5+ years without this issue. Configuration is totally same between vim and nvim.

In nvim with same environment, I can open other types of files as usual, like opening directories or libreoffice files. This issue only occurs to image files (or maybe I haven't met any other bug file types).

It is hard to find related issue or stackoverflow thread. Also as there is no log, there is hardly no point to start with for me.

What would be the source of the issue, or at least, how can I debug..?
