[wsl] Failed to create a temp folder for icon: Os

[mortenscheel]

On Ubuntu 22.04 in WSL2 (Windows 11).

Installed git-butler from deb file, and then ran sudo apt install -y -f as recommended here

Running git-butler results in this error message:

I haven't figured out where it's trying to create a temporary folder. AFAIK my filesystem permissions are all default, and /tmp has the normal 777 permissions.

This appears to be due to the system tray icon attempting to be created, these are the paths it's attempting to use: https://github.com/tauri-apps/tao/commit/ce209d39ab21e493ba98bab83aa7827fa05d7050#diff-b4d52f37e7d6ca7856f2be3e842adc85275e9973dfb85316a5ed1910dccbd368R108

For me, I had to unset XDG_RUNTIME_DIR. I also noticed that /tmp/tao had files owned by root. You may want to fiddle with the permissions there.

im considering removing the tray icon altogether as it's not very valuable as it stands. will ping here with an update
