This may have something to do with these errors at start:

$ ./subsurface
Object::connect: No such signal CylindersModel::dataChanged(QModelIndex, int, int) in qt-ui/diveplanner.cpp:974
Object::connect: No such slot DivePlannerPointsModel::drawProfile() in qt-ui/diveplanner.cpp:977
Object::connect: No such slot DivePlannerPointsModel::drawProfile() in qt-ui/diveplanner.cpp:979

I recommend fixing those next :-)
