[Pharo-project] Strange with Author

I have a small script to build automatically DrGeo release. In this script, I need to set the Author fullName to the value 'DrGeoUserScript'. I have enclosed below the used script. Strangely, the author fullname is not persisted in the image, although I set the author name just before the snapshot of the prepared image. Any idea ? -- Dr. Geo, to discover geometry on Linux, Windows, MAC and XO http://community.ofset.org/index.php/DrGeo
