return 0 in verify_cb gives ssl3_get_client_certificate warning

[Tobias Nissen]

Hi,

using a custom verification callback with AnyEvent::MPRPC I get

  ssl3_get_client_certificate: no certificate returned

if I return 0 in verify_cb. I'm referring to

  http://search.cpan.org/~mlehmann/AnyEvent-6.1/lib/AnyEvent/TLS.pm#verify_cb

Here's a minimal example (keys included):

  http://paste.scsys.co.uk/159837

It's only a warning, but I'd like to get rid of it. Can someone nail
down the problem?

TIA,
Tobias
