Some keys decrypt but not all; not with older version of bitcoin

[lanfeusst]

Hi,
I made today the update to bitcoin 0.10.2.0 from the 0.9.3 version.
My wallet is encrypted and I use Ubuntu 14.04.
When I entered the passphrase to make a transaction, Bitcoin-Qt 0.10.2 closed and in the log there is :

The wallet is probably corrupted: Some keys decrypt but not all.

When I type :

walletpassphrase mypassphrase 120

It does the same : il closes and shows the same message in the log.

Howewer when I start Bitcoin-Qt version 0.9.3 with the same wallet.dat, all works as always and I can do

walletpassphrase mypassphrase 120

without problem or create the transaction that I wanted.

Is it a bug in the newer version of bitcoin ? If not why does it work with 0.9.3 ?

Thank you for your help

This is interested. I have upgraded from 0.9.3 recently as well and did not have problem with decryption. I think it might be related to the version for Ubuntu, however I might be wrong.

I did not encounter people with this problem. I guess you could open a ticket on Github and report about this. However, if you want to upgrade urgently then you can do a workaround.
1) Start Bitcoin-Qt 0.9.3
2) Go to the console and enter: walletpassphrase yourpassphrase 120
3) Enter: dumpprivkey yourbitcoinaddress

4) Start Bitcoin-QT 0.10.2 (let it generate a new version)
5) Go to the console and run: importprivkey yourprivatekey

You can manually just import what you need or everything in the meantime. That should work in theory, however keep backups of the wallets. Watch out when (if) you copy those private keys.
