It's probably an encrypted MPI started with a zero octet.  This
problem is already known, I think.

Workaround: Create a new directory, copy the secret key (in
non-armored from) to "secring.gpg", use "gpg --home . --edit-key" to
change the passphrase.  It's likely that the result is readable by
GnuPG (the bug is triggered with a probability of 1:85 or so).
