A few steps more: when I drop a project file onto the desktop the
following methods are called

PasteUpMorph handleDroppedItem: anItem event: anEvent
ExternalDropHandler lookupExternalDropHandler: anItem
ExternalDropHandler handle: dropStream in: pasteUp dropEvent: anEvent
ExternalDropHandler class defaultProjectHandler

ProjectLoading openOn: aMultiByteFileStream:
"'/home/user/Downloads/CarAndPen.014(2).pr'"

So we have to fix ProjectLoading
