There are two coinbase transactions in 2 consecutive p2pool blocks, of which only the earlier one is shown in bitcoin-qt. When I run “bitcoind listtransactions”, both are shown but in the graphical UI, only the earlier one is shown.
Here’s a screenshot of bitcoin-qt showing just one of the transactions. http://i.imgur.com/ZUJHo.png
