This issue seems similar to bug #985604 and related to the update to FreeHEP 2.4. It still affects the geogebra package in bookworm.
The following patch, similar to the one applied to sweethome3d, fixes this issue: ``` --- a/geogebra/export/GraphicExportDialog.java +++ b/geogebra/export/GraphicExportDialog.java @@ -56,7 +56,7 @@ import org.freehep.graphicsio.emf.EMFGraphics2D; import org.freehep.graphicsio.pdf.PDFGraphics2D; import org.freehep.graphicsio.svg.SVGGraphics2D; -import org.freehep.util.UserProperties; +import org.freehep.graphicsbase.util.UserProperties; /** * @author Markus Hohenwarter ``` Regards, Thiago
