Well, there we see the error:

Unfortunately, the trace does not tell us what went wrong with
`call-process-region'. I've committed a patch to the Emacs repository
improving the trace. Could you, please, rebuild Emacs and rerun the test
with `tramp-verbose' set to 6? The debug buffer might tell us more then.
