bug#36944: Xfce Panel shortcuts after updates might not work

[znavko]

Hello! Sometimes, when Icecat or Pcmanfm-qt update, I am not able to run them from shortcuts I've add to panel as Items (right mouse click - Panel - Add new Item).
This is because applications addresses were changed after update (because guix adds hash to application folder).
This makes me need to delete shortcut and add again.
Xfce is not in account in this. Xfce does not use /home/user/.giux-profile/bin folder for those shortcuts. Xfce uses /gnu/store/hashhashahsh-icecat-60.1/bin/icecat instead. And this is my trouble.

Do you think we can solve this?
