Expiration not valid in PGP 6.5.3

[Per Tunedal]

I created a demo key with expiration in 7 days with the new GPG and 
exported the public key as an ascii-armoured file. Then I imported the key 
to PGP: now the expiration date is set to NEVER! Expiration date is OK when 
looking at properties with GPG.
