Some more info. Installing the configuration of Voyage from Pharo4 itself also breaks the installed Seaside, which was previously installed from the Pharo4 configuration too.
Now when installing the Voyage configuration, it warns about installing Seaside-Core and the conflict with installed version, there are three options: Load, Merge, Cancel. All break the image. I don't see on Voyage configuration a Seaside dependency, so I guess one of its used configurations do so. -- Dr. Geo http://drgeo.eu
