[bug]: xdg-open on Plasma 6 Wayland: Invalid environment block

[xfzv]

What happened?

Plasma 6 was recently stabilized on Gentoo.

After updating (using Wayland session), I'm getting the following error every time I try to open a mimetype that use a Plasma app as default, e.g.

• Gwenview for images:

% xdg-open example.png
kf.kio.gui: Failed to launch process as service: "[email protected]" "org.freedesktop.DBus.Error.InvalidArgs" "Invalid environment block."
Invalid environment block.
Exited with status code: 4
Process failed

• Okular for PDFs:

% xdg-open example.pdf
kf.kio.gui: Failed to launch process as service: "[email protected]" "org.freedesktop.DBus.Error.InvalidArgs" "Invalid environment block."
Invalid environment block.
Exited with status code: 4
Process failed

After digging further, I eventually found that the problem can be solved by either:

• disabling all plug-ins loading in zinit
• keeping plug-ins loading in zinit but disabling ALL_EXPORT Zsh option:

man 1 zshoptions

   Initialisation
       ALL_EXPORT (-a, ksh: -a)
              All parameters subsequently defined are automatically exported.

My zinit config:

declare -A ZINIT
ZINIT[HOME_DIR]="$XDG_DATA_HOME/zsh/zinit"
ZINIT[BIN_DIR]="${ZINIT[HOME_DIR]}/bin"
ZINIT[COMPINIT_OPTS]=-C
ZINIT[NO_ALIASES]=1
ZINIT[ZCOMPDUMP_PATH]="${XDG_CACHE_HOME}/zsh/zcompdump"
ZSH_CACHE_DIR="${XDG_CACHE_HOME}/zsh/zinit"

[[ -e "${ZINIT[HOME_DIR]}" ]] || git clone https://github.com/zdharma-continuum/zinit "${ZINIT[BIN_DIR]}"

source "${ZINIT[BIN_DIR]}/zinit.zsh"
autoload -Uz _zinit
(( ${+_comps} )) && _comps[zinit]=_zinit

zinit ice depth=1 ; zinit light romkatv/powerlevel10k
zinit ice depth=1 ; zinit light jeffreytse/zsh-vi-mode
zinit light zdharma-continuum/history-search-multi-word
zinit ice lucid wait has'fzf'
zinit light Aloxaf/fzf-tab
zinit snippet https://github.com/intrntbrn/icon_customizer/raw/master/dynamictitles.zsh

if [[ ! -d "${XDG_CACHE_HOME}/zsh/fsh" ]]; then
  mkdir "${XDG_CACHE_HOME}/zsh/fsh"
fi

zicompinit
zicdreplay

zinit wait lucid for \
  atinit"FAST_WORK_DIR=${XDG_CACHE_HOME}/zsh/fsh" \
  zdharma-continuum/fast-syntax-highlighting \
  atload"!_zsh_autosuggest_start" \
  zsh-users/zsh-autosuggestions

If I only use this (without any plug-ins loading), no issue:

declare -A ZINIT
ZINIT[HOME_DIR]="$XDG_DATA_HOME/zsh/zinit"
ZINIT[BIN_DIR]="${ZINIT[HOME_DIR]}/bin"
ZINIT[COMPINIT_OPTS]=-C
ZINIT[NO_ALIASES]=1
ZINIT[ZCOMPDUMP_PATH]="${XDG_CACHE_HOME}/zsh/zcompdump"
ZSH_CACHE_DIR="${XDG_CACHE_HOME}/zsh/zinit"

[[ -e "${ZINIT[HOME_DIR]}" ]] || git clone https://github.com/zdharma-continuum/zinit "${ZINIT[BIN_DIR]}"

source "${ZINIT[BIN_DIR]}/zinit.zsh"
autoload -Uz _zinit
(( ${+_comps} )) && _comps[zinit]=_zinit

if [[ ! -d "${XDG_CACHE_HOME}/zsh/fsh" ]]; then
  mkdir "${XDG_CACHE_HOME}/zsh/fsh"
fi

Steps to reproduce

1. Run Plasma 6 with Wayland
2. Use the full zinit config mentioned above with Zsh option setopt ALL_EXPORT
3. Try to open any file that use any KDE Plasma app as default opener with xdg-open $file.ext
4. The Invalid environment block. mentioned error is printed
5. Remove setopt ALL_EXPORT and run xdg-open $file.ext again: no error
6. Add setopt ALL_EXPORT again and only keep the second zinit config (without any plug-in loading)
7. Run xdg-open $file.ext: no error
