Xsane does not save resolution setting between sessions

For some reason, xsane does not save the resolution setting between sessions. By default it goes back to 100. All other settings in the same panel are saved correctly.

Moreover, it shows two options regarding resolution: vertical and horizontal resolution, with values that do not always match. Ideally, just one box should work for both.
