Signature packets without (whatever)

Recently, when checking my trustb I get the following appearing:

gpg: buffer shorter than subpacket
gpg: signature packet without keyid
gpg: buffer shorter than subpacket
gpg: buffer shorter than subpacket
gpg: signature packet without timestamp
gpg: buffer shorter than subpacket
gpg: signature packet without keyid
gpg: buffer shorter than subpacket

Now, I figured that cleaning the keys would probably fix this, but the
question is: how do I find the offending keys?

Or should I just batch-clean the lot?
