FYI: someone just informed me that he magically had 30k and 5k transfers in his wallet. It was this address
http://wavesexplorer.com/address/3PHBX4uXhCyaANUxccLHNXw3sqyksV7YnDz And what is the seed? Try "import account" in your WAVES Lite Client 0.3.0 from github, then click "generate address from seed" and compare the address

With the client 0.3.0 I could reproduce the problem, if you click "generate address from seed" first, then enter the wallet seed, then the password and click "register". Looks like with version 0.3.1 it was fixed. Bad luck for the guys who maybe lost 30k.
Generation on the previous wallet worked perfectly. I have personally tested it on several operating systems on multiple browsers. I always got my address from my seed.
Maybe the guy had a weak personal seed. Perhaps his computer was hacked. Perhaps he used the informal wallet.
No, it didn't. With version 0.3.0 it was possible to click "generate address from seed" with an empty seed (this is still possible in 0.3.1, too), which results in the address I posted, try it yourself. And some guys did this, because there were high transaction on this address. And if you then entered the right seed after it, but didn't click "generate address from seed" again, it was possible to click "register", but the address was not updated (this was fixed in 0.3.1), resulting in an address for the empty seed, which I just posted. I guess this was meant by the release note "Fixed an issue with address generation after seed modification".
