The example Spartan Viewer is broken. Fixed the crash and DICOM loading in T17551. However the example is still broken. The import button points to non existing slots and does nothing. Also opening a file with the open file button loads the file and displays it in the datastorage, but its not shown in the renderwindow until a re-init is triggered in the datastorage. Also the mouse interaction of the renderwindow does not work. Another bug is, that all examples are build and shown in the MITK Workbench. See T17728.
