No, that file doesn't exist.  So it looks like you've located the problem.

I can't, no, because I get the same problem:

mithrandir:~$ gpg2 -kv D15D313882004173
gpg: using classic trust model
gpg: keydb_get_keyblock failed: Legacy key
gpg: error reading key: No public key

Aha.  Okay, I seem to have fixed it, although I still don't really
understand what happened.  On a hunch, I ran:

$ gpg2 --import ~/.gnupg/pubring.gpg

That spat out a bunch of output (tons and tons of those legacy key
messages), and then I ran:

$ gpg2 --import ~/.gnupg/secring.gpg

again.  That prompted me for the passphrase for the private key for
D15D313882004173, and then apparently successfully imported it.  Now, the
gpg2 command works:

mithrandir:~$ gpg2 -kv D15D313882004173
gpg: using classic trust model
pub   rsa4096/D15D313882004173 2009-05-29 [expires: 2017-09-17]

sub   rsa2048/7D80315C5736DE75 2010-09-17 [expires: 2016-03-20]

and now assword works again.

So, something weird about the automated key import process for gpg2?
