Subject: Epiphany fails to launch Evince
Date: Fri, 21 Feb 2020 09:50:27 +0100

Hello,

When running Epiphany on a non-GNOME system with:

  guix environment --ad-hoc epiphany -- epiphany

and opening a PDF, it fails to launch Evince (referred to as
“Dokumentmontrilo” below :-)) and crashes:

--8<---------------cut here---------------start------------->8---
$ guix environment --ad-hoc epiphany -- epiphany

The problem is that ‘gio-launch-desktop’ is not found in $PATH.

As of Epiphany 42, it doesn't rely on Evince anymore for viewing PDFs
(rather, it uses its PDF.js module).  But the problem seems to remain
that displaying PDFs in Epiphany fails outside of GNOME.  On my
ratpoison session, it consistently crashes when visiting PDF URLs.

I'm not sure how to debug this further.

Thanks,

Maxim
