Setting (service home-bash-service-type) causes XFCE to reset it's icon theme from elementary-xfce-dark to Adwaita, despite Adwaita not even showing up in the icon/theme selector. It also locks you out from changing the icon/overall theme, when you click the options they do nothing and that does not get reversed if you remove the service.
To reproduce you just have to
1. Check your current theme with xfconf-query -c xsettings -p /Net/IconThemeName
2. Add (service home-bash-service-type) to your home config and reconfigure
3. Check how the theme changed to Adwaita, you're also unable to revert it back (or change at all).
Everything I could find is mainly aimed at normal distros so the solutions don't work, also it's a pretty bad thing because ideally you'd setup your bashrc in the config file.
