[DRE-maint] Bug#894880: ruby-graphviz: please use HOME (or do not override) instead of G_HOME

[Simon McVittie]

Package: ruby-graphviz
Version: 1.2.3-1
Severity: normal
User: pkg-gnome-maintainers at lists.alioth.debian.org
Usertags: g-home

ruby-graphviz has this in d/rules:

> # Tests try to read /root/.pangorc and fail if we don't set this variable.
> # See #570313 for more details
> export G_HOME=/

G_HOME was a Debian-specific workaround for old versions of GLib not
respecting HOME. Since GLib 2.36, GLib functions that look for the home
directory *do* respect HOME. GLib >= 2.36 is available in oldstable, so
I'd like to remove the G_HOME hack now.

Please investigate whether this is still needed, and if it is, set HOME=/
instead.

Thanks,
