hey,

i followed the exact sequence you described, plus a few variations out of 
curiosity, and could not produce the same skewed results; everything was 
fine.  for reference, i used GNU gzip 1.2.4, uuencode - GNU sharutils 4.2,
PGP for Personal Privacy Version:  unix50i1b.  i used key sizes ranging
from 1024-4096 bits, tried it with pgp2.6.2i and pgp2.6.3is also, tried 
encrypting with several keys, and more.  all of this was done on Solaris 
2.5.1 and RH 5.2.  the only problem i had was that i tried so many 
variations that i got confused at one point and had to double check my 
decoding/decompression process - maybe that's where your problem lies.
