Problems with compatibility between GnuPG 1.2.2 and PGPTools 7.0.3

[Boix Ricart Marc]

The call:

D:\> gpg --list-packets AllBytesPGPC1PGPC1.txt.pgp
:pubkey enc packet: version 3, algo 16, keyid F07BBA5B389F430A
         data: [2047 bits]
         data: [2046 bits]

You need a passphrase to unlock the secret key for
user: "PGPC1PGPC1"
2048-bit ELG-E key, ID 389F430A, created 2003-09-08 (main key ID FE787F04)

:encrypted data packet:
         length: 319
         mdc_method: 2
gpg: encrypted with 2048-bit ELG-E key, ID 389F430A, created 2003-09-08
       "PGPC1PGPC1"
:compressed packet: algo=2
:literal data packet:
         mode b, created 1063009970, name="",
         raw data: 256 bytes

Really can somebody to understand this? :)
Thanks a lot,
Marc
