That is strange, there should be no difference between a shell command
run by Emacs or by hand.  If you copy the above directly from your
*messages* buffer into a shell, then the invocation works?

Are those newlines inserted by your email client, or are there really
newlines embedded into the ditaa command line?  Meaning is Emacs trying
to execute this

| /Users/eric/.emacs.d/org-mode/contrib/scripts/ditaa.jar
| /var/folders/7x/7x730t2UEpec6mgk8rHiyk\+\+\+TI/-Tmp-/babel-777G0f/ditaa-777shg
| /Users/eric/test.png

or this

| /Users/eric/.emacs.d/org-mode/contrib/scripts/ditaa.jar 
/var/folders/7x/7x730t2UEpec6mgk8rHiyk\+\+\+TI/-Tmp-/babel-777G0f/ditaa-777shg  
/Users/eric/test.png

Judging by your formatting I'd guess the former, which seems strange.
