** Description changed:
I'm currently trying to use `docker-compose` (from the Docker snap;
`whereis docker-compose` says `docker-compose: /snap/bin/docker-
compose`; `snap info docker` says `installed: 18.09.9`) with a `docker-
compose.yml` file that's in a subfolder of a hidden directory of my home
folder (think `/home/me/.something/sha0123abc/docker-compose.yml`).
That fails with
+ .IOError: [Errno 13] Permission denied: '/home/me/.something/sha0123abc
+ /docker-compose.yml'
- .IOError: [Errno 13] Permission denied:
'/home/me/.something/sha0123abc/docker-compose.yml'

Things seem to work if I choose a location in a non-hidden directory
instead.
However, this seems like a bug to me; I don't understand a lot about
Snap's/AppArmor's privilege system, but shouldn't a Snap be able to
access the contents of a hidden directory in my home folder?
The context for this is a build system that wraps docker-compose in an
additional tool, which places its config files in a `.something` hidden
directory in a user's home folder. More discussion here:
