bad certificate alerts with accept_ssl()

[von]

For some reason, the client is croaking on some certificate I generate.

And I need to handle this error properly (getting a better message might help understand the certificate problem).

SSLError: sslv3 alert bad certificate

"sslv3 alert bad certificate" probably means the web browser doesn't trust the PerProxy CA.
