ElGamal key restriction

[Matt Kraai <kraai@alumni.carnegiemellon.edu>]

Howdy,

According to http://www.debian.org/devel/join/nm-step2 , ElGamal keys
generated by gnupg versions prior to 1.0.2 are not acceptable.  I
haven't been able to find a justification for this restriction in the
mailing list archives, debian-keyring, or the ChangeLog and NEWS files
of gnupg.  Would someone please explain (or direct me to) the reasons
for this requirement?

Matt
