>From the excerpt of your error_log, I conclude that one of the filters 
preceding the pstops filter (presumably the pdftops filter) failed and wrote 
an error message to standard output (which probably started with the line

Unrecoverable error ...)

which  in turn caused Ghostscript to complain when interpreting this as 
PostScript input.

Please do the following:

(1) post the error log from the beginning of that (or a similarly failing) 
job, beginning with a line containing "autotyping file" or the like.

(2) post (an URL to) the (or a similarly failing) PDF for me to look into,

I need this information to dig more deeply into your issue.
