examining the sig, it happens to be byte-for-byte identical with a sig
on one of the User IDs.

As a result of gpg's (faulty) moving of the sig to the last user ID, we
see the same sig show up after several of the User IDs as well.

observe all the places where this particular sig shows up:

$ gpg --export 0xED34CEABE27BAABC | gpgsplit
$ md5sum * | egrep  '(^848762|(attribute|id|key)$)'
