I’m trying to get devilspie2 to recognize an Emacs window by WM_NAME, which I’m setting with a command-line switch: emacs -q --name=elpher

According to xprop, the properties of the window in question then include the following:

WM_CLASS(STRING) = "elpher", "Emacs"
WM_NAME(STRING) = "elpher"
_NET_WM_NAME(UTF8_STRING) = "elpher"

Ultimately I want my script to set the window’s icon:

if (get_window_name() == "elpher") then
  os.execute("xseticon -id " .. get_window_xid() .. " /home/username/.local/share/icons/papirus-dark/128x128/gemini.png");

debug_print("Window Name: " .. get_window_name());

The icon exists:

~ $ ls -lh ~/.local/share/icons/Papirus-Dark/128x128/gemini.png
-rw-r--r-- 1 username username 3.1K Aug  1 12:30 /home/username/.local/share/icons/Papirus-Dark/128x128/gemini.png

While I’ve had success getting devilspie2 to recognize kitty terminal windows (albeit by class and not name) in order to set icons, in this case devilspie2 reports that something aborted:

~ $ devilspie2 -d
Running devilspie2 in debug mode.

Window Name: xfce4-panel
Aborted at function fopen()
Window Name: elpher

And the icon is not set. Is there a bug somewhere or am I doing something wrong?
