I built a debug version of WeaveCrypto and used the same failing unwrapSymmetricKey inputs and found that it was failing at step 4: http://hg.mozilla.org/labs/weave/file/df8536fd7d1b/crypto/src/WeaveCrypto.cpp#l960 So this means it was able to process the inputs and unwrap the private key but failed to PK11_PubUnwrapSymKey. I double checked the modified dates of the various keys, and they're all created from the same session, so the inputs into unwrapSymmetricKey should all be the same.

And as a sanity check, Tony tried syncing with 1.0b2 (the version he was using before upgrading to 1.0b3pre1 and ran into this problem) and IWeaveCrypto.unwrapSymmetricKey was still failing. So.. still no idea what could be wrong. The server data is theoretically the same (unchanged modified time), crypto is unchanged, passphrase is unchanged..

I double checked with the crypto library used on the weave web interface, and it also fails when trying to unwrap the symmetric key. The 256-byte decrypted value doesn't match the expected PKCS#1 type 2 format.

Seems like two syncs started at the same time because Minefield and Namoroka were open on the same machine and idle triggered syncing. 1. Both Namoroka and Minefield grab the pub/priv keypair at the start of sync 2. Somehow Namoroka decided to start deleting data 3. Namoroka generates a new keypair (slow) 4. Minefield generates new crypto/symkeys because the server was empty (fast) 5. Namoroka finally uploads keypair and sees symkeys existing and stops

Oh, I should note that the above log is from Nov 21st. I'm assuming Namoroka got a weave update and needed to wipe the server. During the Namoroka wipe process, meta/global wasn't updated by the time Minefield ran remoteSetup, so it continued.

http://hg.mozilla.org/labs/weave/rev/8f9308938f3f Check that the cryptometa is unwrappable when syncing; if not purge the key and data and make a new crypto record. This is the recovery step of the bug.

http://hg.mozilla.org/labs/weave/rev/44ceecdd5b86 Avoid concurrent key generation by updating meta/global immediately after resetting the client and have wipeServer not delete the meta collection. Also on detecting a syncid mismatch, sleep to allow remote keypair to be uploaded, and don't force a mismatch on upgrade.
