I have a couple of those unconfirmed tx's from those 1Sochi 1Laxo addresses and they are more than a month old. Gavin posted this about the QT wallet
That is a feature of Bitcoin-Qt. Unconfirmed dust transactions don't enter the memory pool, so they are not relayed, not included in blocks being mined, and not displayed by the wallet.
If I recall correctly, if they DO get mined into a block by somebody then they are displayed. Ignoring them and not adding them to the wallet in that case might be a nice feature, although today's dust might be tomorrow's treasure if prices rise another couple orders of magnitude.
Why do these tx's show up on the Armory wallet at all and why are they there more than a month later? Normally they disappear after a couple days. Does it mean they are being rebroadcast or is it some other reason?
