I just checked the behavior of my LiDE220. I plugged the scanner into USB3, started xsane and set it to full color at 300dpi and pushed the scan button. Up popped the "invalid argument" dialog. I then acquired a preview which worked and thereafter xsane works fine. I could not reproduce the error again by closing and restarting xsane or replugging the scanner (multiple times). All other front ends I tried worked.
Your newest symptoms sound like the issues pre 1.0.25. Are you sure of the version you're running? Try renaming or deleting your ~/.sane directory.
