At a first look there as some obvious reasons for this:
1. in main.cpp KApplication is created always with Gui enabled - this is easy
to fix
2. UMLApp uses several objects like the QPrinter object, which creates a
QWidget object. It looks they depend on an X-Server. The question is if it is
possible to avoid such object creations or if not if it is possible to use some
memory based gui output device to avoid the x-server dependency.
