Zodiac/SqueakSSL plugin on OSX with Pharo 2.0 error

accept

"Do the SSL server handshake."

| count result |

self resetEncryptedBuffers.

count := 0.

connecting := true.

[ self sslSession isConnected ] whileFalse: [

count := self readEncryptedBytes: in startingAt: 1 count: in size.

result := self sslSession accept: in from: 1 to: count into: out.

result < -1 ifTrue: [ 

^ self sslException: 'accept failed' code: result ].

result > 0 ifTrue: [ 

self flushEncryptedBytes: out startingAt: 1 count: result ] ].

connecting := false

Looking at the SqueakSSL plugin source code: -5 indicates a generic SSL exception/error, any ideas what this could be ? My self-signed certificate works fine when run using openssl ( openssl s_server -accept 8443 -cert server.pem -WWW ).

Thanks
