Obama & Iraqi Minister? Another Gaffe?

What exactly did Iraqi Minister tell Mr. Obama? Did Obama lied or the media is going to conisder this misinformation another gaffes? why is it that Iraqi Minister Zebari recalls different discussion?

I speculated that something seemed odd about Barack Obama’s account of his
conversation with Iraqi Foreign Minister Hoshay Zebari. Obama said that Zebari
didn’t express any concern about Obama’s immediate withdrawal plans. Well,
according to Zebari that is a lie.

Jennifer Rubin, from Commentary Magazine continue to write:

There seems little reason for Zebari to lie about his private meeting with
Obama. That leaves us to conclude that Obama either didn’t listen to or didn’t
understand what Zebari said or misrepresented what he heard from the Foreign
Minister. That is deeply troubling. An explanation seems in order from Obama.

UPDATE I: From ABCnews blog:

"But today comes this report that Zebari told the Washington Post "that he had some frank talk for the candidate: 'The foreign minister said ‘my message’ to Mr. Obama ‘was very clear...Really, we are making progress. I hope any actions you will take will not endanger this progress.’

UPDATE II: From Corner
Beyond that, aren't Obama's comments to Zebari — presuming they're being characterized accurately — a glaring contradiction of the Obama campaign's constant declaration of "profound differences" with McCain on the Iraq War? Isn't a large chunk of his support from the Democratic grassroots built on this notion that a President Obama would bring the troops home quickly?
