SUMMARY


STEPS TO REPRODUCE
1. Create executable file ~/bin/bg-dbl-clk-test with contents:
----8<-cut-here-----------------------------------------------------------------
#!/usr/bin/env bash

printf "[%s] first arg is: “%s”\n" "$(date)" "$1" > ~/bg-dbk-clk-test.out
----8<-cut-here-----------------------------------------------------------------
2. In Dolphin, set Background: Double-click triggers: to "Custom Command".
3. Set the custom command to: $HOME/bg-dbl-clk-test {path}
4. Open a remote folder in Dolphin and double-click the background. I used:
fish://sam-birch@buildvm:22/home/sam-birch/projects/linux/arch/arm64/boot/dts/rockchip/
5. Look at the contents of ~/bg-dbk-clk-test.out

OBSERVED RESULT
[Thu Jun 12 11:17:02 AM EDT 2025] first arg is: “”

EXPECTED RESULT

“/run/user/1000/kio-fuse-gPPzTW/fish/sam-birch at buildvm:22/home/sam-birch/projects/linux/arch/arm64/boot/dts/rockchip”

ADDITIONAL INFORMATION
It'd be cool to get the translated kio-fuse path, but I'd also be happy with
the raw KIO URL — I can always make a wrapper script that does the kio-fuse
mount and looks up the path. Here's my little script that does that, in case
it's of interest:
----8<-cut-here-----------------------------------------------------------------
#!/usr/bin/env fish

function main -a url
    dbus-send --print-reply=literal --type=method_call --dest=org.kde.KIOFuse \
        /org/kde/KIOFuse org.kde.KIOFuse.VFS.mountUrl string:$url \
    | string trim -l
    printf "\n"
end

main $argv
----8<-cut-here-----------------------------------------------------------------
