I definitely fixed my problem on my 650U on Ubuntu 12.04 with the help of the sane-devel mailing list. Don't know if that method (that requires re-defining the motors parameters) would apply to the Lide20 also, and I don't know if using wrong values on the lide20 could damage the scanner hardware, so I think someone experiencing this bug better writes directly to the list and report here the results
