This patch doesn't fix the actual cause of this bug. The problem stems
from commit 693dda67 [1], and I've just pushed up a fix in commit
a79fd4be [2].
Thanks to both of your for raising this issue.

ob-core: allow language specific header arguments in properties
* lisp/ob-core.el (org-babel-insert-header-arg,
org-babel-parse-src-block-match): Replace `if' with empty else part
by `when' for readability. (org-babel-params-from-properties):
Inquire for language specific and default header properties.
Language specific header properties take precedence over default
header properties and old-style header property specifications.
This allows for header arguments to be specified as
properties (including inheritance).
#+PROPERTY: header-args :cache "no"
#+PROPERTY: header-args:R :session "*R-property*"
:PROPERTIES:
:header-args: :cache "yes"
:header-args:R: :session "*R-drawer*"

fix babel merge params bug from commit 693dda67
The `org-babel-params-from-properties' command was calling
`org-babel-merge-params', the output of which was then being fed back
to another call to `org-babel-merge-params'. The merge params
function is not designed to allow this form of recursive calling, and
as a result many variables were being set to empty values.
The first noticed side effect of this bug was the breakage of the
org-babel-load-file command, which relies on default header
arguments (namely :tangle), which were overwritten by the bug above.
The fix involved having the `org-babel-params-from-properties'
function return a list of alists, which may then all be handed to the
top-level merge-params call.
* lisp/ob-core.el (org-babel-params-from-properties): Now returns a
list
of alists and does *not* call `org-babel-merge-params'.
(org-babel-parse-src-block-match): Handle new list of lists output of
`org-babel-params-from-properties'.
(org-babel-parse-inline-src-block-match): Handle new list of lists
output of `org-babel-params-from-properties'.
* lisp/ob-exp.el (org-babel-exp-src-block): Handle new list of lists
output of `org-babel-params-from-properties'.
(org-babel-exp-non-block-elements): Handle new list of lists output
of
`org-babel-params-from-properties'.
* lisp/ob-lob.el (org-babel-lob-execute): Handle new list of lists
output of `org-babel-params-from-properties'.
