Hi!

I'd like to run browsers in `guix environment` which seems to be a good
idea! :)

IceCat has been discussed in the past.  Now I'd like to run
WebKitGTK-based browsers.

Let's try with Eolie for now, since it seems to have less issues than,
say, Epiphany.

--8<---------------cut here---------------start------------->8---
$ guix environment -C -N --expose=/etc/machine-id --expose=/etc/ssl/certs/ --share=$HOME/.local/share/eolie/=$HOME/.local/share/eolie/ --ad-hoc dbus eolie coreutils -- env DISPLAY=$DISPLAY SSL_CERT_DIR="$SSL_CERT_DIR" SSL_CERT_FILE="$SSL_CERT_FILE" eolie

(org.gnome.Eolie:1): Gtk-WARNING **: 12:50:06.747: Could not find the icon 'go-previous-symbolic-ltr'. The 'hicolor' theme
was not found either, perhaps you need to install it.
You can get a copy from:
	http://icon-theme.freedesktop.org/releases
[ERROR] 2020-04-21 12:50:07 DatabasePhishing::__save_rules():Expecting value: line 1 column 1 (char 0) -> b'error code: 1020'
[WARNING] 2020-04-21 12:50:08 TaskHelper::__on_request_send_async(): g-io-error-quark: Operation was cancelled (19)
[ERROR] 2020-04-21 12:50:08 DatabaseAdblock::__on_load_uri_content(): https://adaway.org/hosts.txt
--8<---------------cut here---------------end--------------->8---

It seems to work well except for TLS certificate validation.  I
guess the certificate files cannot be found in the container since they
can be found in a --pure environment:

--8<---------------cut here---------------start------------->8---
$ guix environment --pure --ad-hoc dbus eolie coreutils -- env DISPLAY=$DISPLAY eolie
--8<---------------cut here---------------end--------------->8---

so I presume the certificate errors are not due to my environment and
'bin/eolie' exports the right environment variables.

My guess is that webkitgtk, glib-networking, glib or gnutls tries to
fetch the certificates in a well-known location.

Any idea about this?
