Hi

Try to upgrade your SAGA version, because you are an ubuntu user, my advice
will be to use the ppa repository of Johan Van de Wauv

sudo apt-add-repository *ppa:johanvdw/sagacv*


I can't tell you more because i only use GRASS through spgrass6 and it's
have been a long since the last time i tried SAGA (can't build it from svn).
