Bug in SSL.Context.load_verify_locations ?

I heve the following code:

  ctx = SSL.Context("sslv3")
  ctx.load_verify_locations("filename.pem")

It is failing with:

  64293:error:0B064071:x509 certificate routines:ADD_CERT_DIR:invalid directory:/usr/src/secure/lib/libcrypto/../../../crypto/openssl/crypto/x509/by_dir.c:187:

I think this is beacuse of:

    def load_verify_locations(self, cafile=None, capath=None):
        return m2.ssl_ctx_load_verify_locations(self.ctx, cafile, capath or '')

You are passing an empty string to X509_STORE_load_locations, when it
should be NULL instead.

Also it might be nice if m2crypto threw an exception when OpenSSL
reported an error.

Cheers
