This happens in both master and core-updates, although it seems to fail with a
different error in the former (see https://issues.guix.gnu.org/39324). It also
happens in both real machine and virtual machine.
## Steps to reproduce
Assuming you are using the Guix System with GNOME:
1. Go to Activities → Show Applications (nine dots button) → All → Weather
## Expected result
GNOME Weather starts.
## Unexpected result
You see the GNOME Weather application menu loading next to the "Activities"
button in the GNOME desktop. But, after a few seconds, the application menu
disappears and GNOME Weather never starts.
## Additional information
In my real machine, running GNOME Weather from a terminal fails too with the
following message:
```
$ gnome-weather
Unsatisfied dependency: Gdk
```
In a virtual machine, however, GNOME Weather starts when run from a terminal.
In both, real and virtual machines, GNOME Weather starts when run from the
minishell (press Alt+F2 and enter gnome-weather).
## System information
```
GNOME Weather 3.34.0
