Looks like your switch doesn't support the stat() operation, which
sftp(1) uses before the download and will abort the download if the
stat fails.

You can try this patch, which is against OpenBSD's -current but should
apply to 4.7 and 4.6 as well (and yeah, I know "goto" is bad, this is
the minimum change to test the theory.)

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
