lios hangs just after recognizing the scanner

As reported on https://bugs.debian.org/910144 :

File "/usr/lib/python3/dist-packages/lios/scanner/scanimage_driver.py", line 102, in set_scan_area
  self.y = int(self.max_y)
AttributeError: 'DriverScanimage' object has no attribute 'max_y'

I guess this could be that for this particular scanner scanimage perhaps does not report a -y option?
