I can't help much now, sorry. The problem did go away for me, months ago. I've stopped using 1Password, and upgraded to Snow Leopard, but the problem disappeared some time before I did either.

I did just about everything I could think of with the keychain and I honestly don't remember the circumstances that resolved the problem. I do remember being surprised when it seemed to resolve itself - I didn't do anything immediately beforehand that I could recall, though I had been in previous days. I suspect something that was using the keychain wasn't playing nice.

Sorry I can't help much. At least I can offer hope - I'm fine now.
