invalid gpg key revocation

[auto15963931 at hushmail.com]

I am 99.9% sure no one has gotten access to my machine or my keys. 
If they had, I have to believe that there would have been more 
damage done than this, and that does not appear to have happened. I 
mention the details, which may seem irrelevant, only because 
sometimes the devil is in the details.  This event has in fact 
occurred, and I need to figure out how to explain it and prevent 
it. There was no revocation certificate for the key in question. 
There has to be another explanation. If this was user error, then I 
want to find that as well. What can be looked at on the revoked key 
to see how or under what circumstances it was revoked? Thanks.
