Transaction not getting confirmed, help!

[1PFYcabWEwZFm2Ez5LGTx3ftz]

I withdrew money from bitcoin-central (not sure if this is important), and I see the transaction in my bitcoin client (Bitcoin-QT), however it is not getting any confirmations after an hour now. (transactions made before this one are getting confirmations added normally).
Transaction ID as given by QT client and bitcoin-central is 34c1347a3a395a992210f9348b2874327e20f91390b594e39dfa4a2a5cfc44be , but blockchain.info says "transaction not found".

It got the first confirmation after an hour, but why did this happen?
There were several blocks created after the transaction, but it was not encased in any of them. Why?

Could be based around the transaction fees.

Things with a transaction fee are given priority processing. I'm guessing they don't add anything above the minimum fees for the transaction. Meaning it gets a low priority compared to all the smaller transactions at minimum fees, as they represent a larger percentage of the total transaction.

My guess is that they didn't add ANY fee. Does that mean that transactions without any fee has the potential to be delayed substantially?

Yes I am awaiting confirmation on transaction for over 24h ( http://blockchain.info/tx/bda79bc758b7212c28f2bc5d8ad48a534ae96a870e5c94faf35754ced1444ffc ) but i know that it will go in to a block. It is just a matter of time when that will happen.
