Cannot Set the Expiration Date on Secure Subkeys

[David Botham]

All,

I am having problems setting the expiration date on my private subkey.
I can set it, however, when I quit and then re-edit the key, the
expiration date is set to 'never', instead of what I had set it to in
the previous editing session.  

I am missing something?

Here is a transcript of my gpg sessions that demonstrate this problem
(key ID A734F56B is the one that switches back to 'never'):

Is this correct? (y/N) y
Really create? (y/N) y
We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.
