Angela Merkel and Nicolas Sarkozy often seen chatting. What language?

Whenever there’s a news clip of yet another Euro crisis meeting, we always seem to see Angela Merkel and Nicolas Sarkozy chatting together.

They’re probably exchanging meaningless smalltalk for the sake of the cameras but what language would they be speaking?

This was discussed pretty extensively a few months ago, in this very forum.

Oh yes. Sorry, I should have searched better.
