Blockchain.info had (or still has?) some problems lately. If you created the TX there it might be an issue on there end not relaying the TX further for some reason. Did you try pushing it elsewhere?
I have gotten the raw form for this transaction and pushed it out at coinb.in. It does show that it is successfully broadcasted but a quick search through major block explorers show that it can't be found.
Edit: Seems like it has now been confirmed and can be found at all block explorers. However, it's still weird that I can't find it else where either. Perhaps those explorers had a different policy.
