This happens in both master and core-updates, although I don't know if the
former fails for the same reason. 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
2. Click on Maps
## Expected result
GNOME Maps starts.
## Unexpected result
GNOME Maps does not starts. You see the GNOME Maps application menu loading
next to the "Activities" button in the GNOME desktop for a few seconds, but the
application never starts.
## Additional information
In both, real and virtual machines, GNOME Maps starts when run from a terminal.
It prints the following message though:
```
$ gnome-maps

```
In both, real and virtual machines, GNOME Maps also starts when run from the
minishell (Alt+F2 and type gnome-maps).
## System information
