A log with SANE_DEBUG_CANON=255 could be helpful, too.

Looks like they removed the debigging symbols. So we can't do much
debugging.

Looks like the SCSI function gets an invalid buffer or similar.

However, the backtrace doesn't seem to be correct as get_select_fd
doesn't call sanei_scsi_cmd2.

Looks like work for the canon maintainer :-)
