I tried to reproduce this bug.  It was very difficult for me, but I
managed to reproduce it this afternoon.

My experiment is following your scenario with my configuration of
GnuPG.  My configuration of GnuPG is as same as:

	http://keyring.debian.org/creating-key.html

(It looks like your configuration has preference of SHA512, though.)

I used 1400-byte long passphrase, and I got same error.

Are you using such a long passphrase like mine?
