Using Bitcoin-Qt (and bitcoind) v0.6.3 from the PPA [Ubuntu 12.04 x64].
Have tried launching a freshly compiled Bitcoin-qt also.
Despite this and a -rescan, the client doesn't seem to want to download past blk 192528
I use Bitcoin-qt just to downloads blocks with an unused wallet.dat. I run it with Armory 0.81-alpha attached.
Strangely, Armory seems to be downloading new blocks fine. It also registers new transactions (after 192528). The height currently is 192885 which matches blockchain.info.
However, from Armory I cannot broadcast transactions to the network - but only from select wallets. I presume this is because Armory tells my client that a transaction is taking place many blocks ahead (in terms of transaction balances) of where the official client thinks it could be; I cannot send coins from an address which has only received coins AFTER block 192528, however, an address which has held some value since at least block 192528 will generate an accepted transaction.
Resources I've found prior to this:
https://bitcointalksearch.org/topic/06-bitcoin-qt-stuck-at-block-176947-78307 [happened april 23ish]
https://github.com/bitcoin/bitcoin/pull/1196 [apparently fixed the issue]
Anyone have any ideas? I'll try not re-downloading the blockchain for a little while so any debugging/info gathering type thing needing to be done can be.
