This means that you discovered a bug either in sanei_scsi.c or in the
avision backend ;) More technically: It means that the function
sanei_scsi_cmd in the sanei_scsi library was called with an "illegal"
SCSI command. This function receives the SCSI comamnd block and possibly
a write data block associated with this command from the caller;
sanei_scsi_cmd needs to figure out (or to guess, if you prefer that) the
size of the SCSI command block; if this guessed size is less than the
parameter src_size, the program is stopped by an assert().

Rene, do you have any idea where this could happen? Stefan, if you run 

	export SANE_DEBUG_AVISION=255
	scanimage -d avision:/dev/scanner

we might get, what happens.
