I'm really no expert concerning the epson backend so just a guess:

This is "set option `source'".

This is from send(), called by reset(), called by handle_source.

This looks like the crash occurs in sanei_scsi, but I'm not sure.
Maybe the user can put some more DBG-Statements e.g. at the end of the
OS/2 sanei_scsi_cmd2 to be sure. By the way, this code has the
following intro:
/* XXX untested code! */ 

:-)

I don't see an obovious problem here, but maybe Karl Heinz Kremer does.
