I think it just became a Guix-specific question, because I have a whole 
bunch of different 
$HOME/.local/share/applications/userapp-IceCat-*.desktop files; it looks 
like the guix package manager is generating a new one every time there's 
a version upgrade of IceCat.  So, there's a now an issue of how I make 
sure any changes I make to the desktop file survive future version upgrades.

(I've also discovered I have a $HOME/.config/autostart/icecat.desktop 
which doesn't point to the latest installed version of the executable, 
which is going to be a whole other bunch of headaches.)
