mbed-client-linux-example gives error when DTLS handshake is delayed

I have noticed that when running 'mbed-client-linux-example' on my Ubuntu 14.04 machine to talk to the mbed Device Connector, if I delay the client 'Certificate' message in the DTLS handshake by a few seconds, the flight of messages that include 'Server Hello done' is retransmitted by the server. I think that is fine according to the DTLS spec. The handshake eventually completes, but after some time (usually within the next minute when /Test/0/D reaches 5), error messages show up in the output console:

Is this a bug in mbedTLS?
