invalid user ID when a revoked key is listed after a good key #35

My gpg --lisk-keys lists a revoked key after my current key.

The current implementation for isvalid:

            for line in out.split('\n'):
                record = line.split(':')
                if record[0] == 'pub':
                    trust = record[1]
            if trust not in trusted:
                return False

only checks the trust level of the last found key, so in my setup I'm getting the "invalid user ID" error.

It looks like LBYL to me: code hard to implement that miss some cases. Should the EAFP style be used instead by just trying to access the password store, and catching an exception as needed? I haven't read the project history I bet this code is here for a reason.
