Bug report, since I can't find a logical place to put this under http://github.com/blockchain:

When I tried to push the following transaction to http://blockchain.info/pushtx:

Code:
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

The sigs all validate just fine. Lost the privkeys unfortunately. Any idea what's up?

Feature suggestion - Blockchain Wallet API List Addresses should include an optional field $confirmations

Is there any way to pull full raw transaction or block data in hex? I'm trying to use http://blockchain.info/rawtx/$tx_index but the scriptsig and scriptpubkey are missing. Being able to pull the information is the same format as sendrawtransaction would be very useful.

I'v added a scripts parameter and confirmations parameter to /rawtx and /merchant/list.

Is it redeeming a multisig transaction? Signature validation for P2SH/multsig scripts is untested, i'm not sure if bitcoinj can validate them or not.

theymos's answer here from September seems to suggest it doesn't (although I certainly don't know).

Can you add on the android app the possibility to take brainwallets / privatekeys from clipboard? (now it is possible only from qr codes)

I've opened the Chrome app and I've received a popup suggesting me to switch to a newer version of the app: https://chrome.google.com/webstore/detail/blockchain/glaohkkooicollgefkkmndjcbblominl/reviews

Also, I've found on twitter that a native app for OSX has just been released: https://itunes.apple.com/gb/app/blockchain/id688882038

Are these legit?

Yes, it was a multisig. It's strange that validation is failing now; I remember it working just fine before. Or maybe my memory is bad and it was just the single-sig transactions that worked.

Why isn't there an option to disable the beep sound? I thought it used to be possible, but I can't figure out how to any more. Seems idiotic to force that sound on users.

Had some duplicate payment notifications.  Unsubscribed and resubscribed lets see if that works.

Also, I use QR scanning quite for watch only address, please remove the secondary password prompt from coming up when my input is from ONLY one (or more) watch only address.  There is no point to decryption the private keys for my other address that are saved in the wallet.
