After asking in the #gnome channel on freenode, the problem is likely
caused by GNOME Shell using inotify to watch the $XDG_DATA_DIRS
referenced $HOME/.guix-profile/share/applications directory.   The
problem is that the inode of such directory will never change, as it
points to the current profile under /gnu/store:

--8<---------------cut here---------------start------------->8---
$ ls -id $HOME/.guix-profile/share/applications
72653730 /home/maxim/.guix-profile/share/applications/
maxim@hurd ~/src/guix$ realpath $HOME/.guix-profile/share/applications
/gnu/store/ph6a7fy735w5nycmf3za77m6v3g0r7xb-profile/share/applications
maxim@hurd ~/src/guix$ ls -id /gnu/store/ph6a7fy735w5nycmf3za77m6v3g0r7xb-profile/share/applications
72653730 /gnu/store/ph6a7fy735w5nycmf3za77m6v3g0r7xb-profile/share/applications/
--8<---------------cut here---------------end--------------->8---

Any applications making use of inotify to discover changes (to plugins,
for example) is at risk of having the same problem in Guix.

I don't currently have an idea of how we can fix this.

Maxim
