I'm not sure if it's the same problem, but there is the following
entry in the ChangeLog:

2002-11-13  Ulrich Deiters <ukd@xenon.pc.uni-koeln.de>

	* modified the Canon SCSI backend (now version 1.10):
	* backend/canon.c, canon-scsi.c: Added support of focus control for
	  the FS2710 film scanner.
	  backend/canon-sane.c: Set handler_arg in sanei_scsi_open() calls
	  to zero to avoid crashes with Mandrake Linux 9.0
So I guess the next SANE version may work. If you don't want to work
you can try the latest snapshot from

If this works for you, can you please tell us? Maybe the Debian
maintainer wants to apply the patch used in the canon backend in the
Debian package.
