Duplicate problem when labeling addresses with Bitcoin-qt 0.7.1

[juhakall]

I have a bunch of receive addresses on my wallet, mostly for different mining pools. Sometimes when renaming a label, another label undergoes the same rename operation. I investigated this more closely and noticed that every time I rename the label of a certain address, it always causes the additional renaming of a certain other address. For example, every time I rename my Deepbit address, my Mt.Gox address is renamed to whatever I renamed the Deepbit address to. The other label isn't actually permanently renamed, because it reverts to it's original name after I restart the client. This is certainly a bug, and I could help debugging it if I had some instructions.

Can you verify, if this is the same bug as:
