The problem results from an incompatibility between Xorg 7.3 and the driver that is supplied by the Ubuntu package. The newest development version (0.7.9-7 at the moment) contains a temporary workaround for Xorg 7.3.
Therefore a workaround for the bug is: Download the most recent development sources from the Linux Wacom Project ( http://linuxwacom.sourceforge.net/ ), compile and install them.
However the workaround provided by the sources is not that perfect. The lines I draw in Xournal are very ugly. I managed to reolve this issue by deactivating "Use XInput" in the Options tab.
