Yes, this fixed. I actually did:

-        sys.stderr.write(err)
+        sys.stderr.write(str(err))
+        sys.stderr.write("\n")

It is now printing:
	b''

I added the \n print to avoid it to be mixed with the "writing output"
prints.

No idea how to make sense from it - but clearly, the error report
logic require some care ;-)

Thanks,
Mauro
