bug#41196: Xfce panel, exo-open: launching applications not working

[Jan]

Hello,

while clicking on icons on Xfce panel, it fails to launch applications
and throws "Couldn't run
command /gnu/store/*hash*-exo-0.12.6/bin/exo-open --launch *Application
name* %u There's no such file or directory".
I thought I reported the issue somewhere, but my memory tricked me and
I confused the issue with the "gio-launch-desktop" bug, which was
recently resolved. If this can be resolved by a simple wrapper, unlike
the "gio-launch-desktop" bug, I can try fixing it.

By the way, the issue is present for like 7 months already. It seems
something failed during making the 1.1.0 release and Guix as a
distribution needs better procedures for handling the release process
to avoid such bugs in the future. A checklist would be good. Maybe
making a "Tests" page in the manual, something with the ability to 
modify the status of test:
* panel: works
* setting wallpaper: unknown/not tested yet
etc.

Hello,

the same problem happened to me right now, but it is not related to any
versions or updates in Guix. In fact, I just did an aggressive "guix gc",
which removed the referenced exo version from the store. The path is
actually stored in my
   $HOME/.config/xfce4/panel/launcher-19/15993349933.desktop
which is not changed upon updating xfce. As long as the corresponding
exo-open is still available in the store, clicking the icon will work;
"guix gc" (after deleting the profile generations where this exo version
was referenced) will remove it from the store.

I do not see what we could do inside Guix to solve the problem.
Personally I simple replaced
   /gnu/store/*hash*-exo-0.12.6/bin/exo-open --launch *Applicationname* %u
by
   *Applicationname* %u

It works at least for (equal? *Applicationname* icecat).
