It may be that the fix I pointed to in the previous email will change
this (who knows? it may even fix it :-) ) But there is one additional
point that you might want to check.

It looks as if you are creating temp files under /var/folders/2y on the
remote: are you sure that a) the structure exists and b) permissions are
set correctly?

Do you have the /var/folders/2y structure on the local host or only on
the remote? If only on the remote and the source block is running
locally (because of the funcall bug), that would sort-of explain this
behavior.
