The patterns in the "bogus" signature looked weird (kjsl output):

  sub  2048g/AC0E538A 1998-04-28
       Key fingerprint = F5AF 74B5 3257 FB0B 85DA  AAD6 B3D3 34D5 AC0E 538A
  sig  0x18  12F506C8 2003-12-17 [keybind, hash: type 2, 2d 09]
  sig  0x18  12F506C8 2003-12-17 [keybind, hash: type 2, 2d 09]
  sig  0x18  12F506C8 1998-04-28 [keybind, hash: type 2, 3d 0a]
  sig  0x18  12F50910 2003-12-17 [invalid signer? corrupted signature?, hash: type 2, 2d 09]

and _this_ looked even weirder (GPG 1.2.4 output):

  sub  2048g/AC0E538A 1998-04-28
       Key fingerprint = F5AF 74B5 3257 FB0B 85DA  AAD6 B3D3 34D5 AC0E 538A
  sig!        12F506C8 2003-12-17   Peter Sjoberg <peters techwiz.ca>
  sig!        12F50910 2003-12-17   [User id not found]

Except where the issuer is irrelevant.
