Same problem (Preview window not usable/empty with Canoscan N670U). When preview window option was turned of in previous session and is turned on, problem shows up. One has to keep the option turned on and to restart xsane to get a useable preview window, closing the bad preview window and turning it on by selecting the show preview option does not recover the window.
