Double Dribble?

[Jimgolf]

I frequently see players accidentally contact the ball on their hip or thigh while dribbling. When the ball is in contact with the hand and the hip simultaneously, and the player then dribbles again, is this a double dribble?

The reason I ask this is that I see players do this all the time, but rarely see a violation called. Is this considered a fumble or interrupted dribble or something?
