Hi,

Karl Heinz Kremer will probably comment on this more specifically.
Just some comments:

This seems to be the problem. There are some hits in the sane-devel
archives about this error and my impression was, that it may be some
sort of SCSI problem.

This time the type is different (?)

This shouldn't happen in any case. Karl Heinz, do you think the
segfault happens in epson.c or sanei_scsi.c?

Yet another type. Maybe the backend gets garbage from the SCSI-system
or the variable is uninitialized?

The error was the same with the Mikrotek? I can't believe that. Or are
you referring to the "segmentation fault"? This just means, that there
is a bug in the code that lead to an forbidden access to memeory.
