can be fixed by a rescan
...

1) got to console ...
2) type "wallet_resync_blockchain"
3) wait 30-60 minutes

Do you mean wallet_rescan_blockchain ?

Oh .. yhea ..
just figures "rescan" should also work

you can read the progress in 'getinfo'

I have this issue too. 0.4.7 has this bug on importing old backup wallet

So if I export a wallet in JSON from Windows, shouldn't I be able to import it in Ubuntu?

Actually I tried to import wallets exported with 0.4.7 to 0.4.7 client and I get this even on Windows...

Can someone tell us what is the most STABLE environment? I am very nervous about keeping my wallet up to date.

I'm getting this:

Finished scanning for new transactions.
