I see what the problem is, but I'm baffled as how you made that key.
The problem is that the key is a secret key with public subkeys.
There is no such thing.  Of course, GnuPG shouldn't bus error on it,
but at the same time, this key is likely corrupt.

What happens when you try this with the 1.2.5 release candidate?
