I have no idea if "other\n\"string\"\nlines" may be passed 
`org-babel-read', but it is not discarded by the current regexp:

"^[[:space:]]*\"\\(.*\\)\"[[:space:]]*$"

Is there a reason why it is necessary to call `read' twice on the same 
content? From my point of view, result of first call may be returned.

Does `read' have other role than unescaping backslash-protected 
characters? Likely it can be done by `replace-regexp-in-string', see the 
attachment. I have tried regexp on the following string:

    (let ((cases '(("" . nil)
	       ("\"" . nil)
	       ("\"\"" . t)
	       ("\"\\\"" . nil)
	       ("\"\\\\\"" . t)
	       ("a" . nil)
	       ("\"a\"" . t)
	       ("\\\"a\\\"" . nil)
	       ("\\\"a\\\\\"" . nil)
	       ("\"a\\\"\"" . t)
	       ("\"aa\\\"bb\"" . t)
	       (" \"aa( bb\"" . t))))
