How did Judas die?

I have included this one simply because it was the first bible difficulty taught to me around thirty years ago. We have two versions of the story, which one is correct?

(Mat 27:3-10 NIV) When Judas, who had betrayed him, saw that Jesus was condemned, he was seized with remorse and returned the thirty silver coins to the chief priests and the elders. {4} "I have sinned," he said, "for I have betrayed innocent blood." "What is that to us?" they replied. "That's your responsibility." {5} So Judas threw the money into the temple and left. Then he went away and hanged himself. {6} The chief priests picked up the coins and said, "It is against the law to put this into the treasury, since it is blood money." {7} So they decided to use the money to buy the potter's field as a burial place for foreigners. {8} That is why it has been called the Field of Blood to this day. {9} Then what was spoken by Jeremiah the prophet was fulfilled: "They took the thirty silver coins, the price set on him by the people of Israel, {10} and they used them to buy the potter's field, as the Lord commanded me."

(Acts 1:18-19 NIV) (With the reward he got for his wickedness, Judas bought a field; there he fell headlong, his body burst open and all his intestines spilled out. {19} Everyone in Jerusalem heard about this, so they called that field in their language Akeldama, that is, Field of Blood.)

The usual explanation or harmony is that he hanged himself and the rope broke and his guts spilled out. J P Holding has a more intriging version in which he hanged himself and his body swelled up as it would in the heat (seen any dead dog corpses?). Either way, it is the same event reported from two perspectives.
