This is, i believe related to the general problems I have been seeing
with the processing of tables passed as arguments to babel blocks vs.
the same tables passed to `call' lines. For example:

#+BEGIN_ORG
#+name: ptable
| head1 | head2 |
|-------+-------|
| a     |     1 |
| b     |     2 |

#+name: ptable-mirror
#+BEGIN_SRC python :var t=ptable :results value :colnames no
	return t
#+END_SRC

#+RESULTS: ptable-mirror
| head1 | head2 |
| a     |     1 |
| b     |     2 |

#+call: ptable-mirror()

#+RESULTS:
| head1 | head2 |
| a     |     1 |
| b     |     2 |

#+call: ptable-mirror(t=ptable)

#+RESULTS:
| head1 | head2 |
|-------+-------|
| a     |     1 |
| b     |     2 |
#+END_ORG

As you can see, the handling of headers/colnames is different in a
`call' depending on if the argument is specified explicitly or not.

BTW, changing `colnames no' to `:colnames yes' results in:

#+BEGIN_ORG
#+call: ptable-mirror(t=ptable)

#+RESULTS:
| head1 | head2 |
|-------+-------|
| head1 | head2 |
|-------+-------|
| a     |     1 |
| b     |     2 |
#+END_ORG
