[Gchemutils-main] Problem importing old gcrystal files is not fixed by version 0.12.12

[Julien Cubizolles]

I was finally able to build 0.12.12 but this version doens't fix the bug
I noticed a few weeks ago : when loading "old" gcrystal files, the
lattice is displayed but the atomes are not.

Here is an example of such a file (ice structure)

<?xml version="1.0"?>
<crystal><generator>Gnome Crystal 0.7.2</generator><lattice>face-centered 
cubic</lattice><cell a="637.4" b="637.4" c="637.4" alpha="90" beta="90"
