I tried to debug a ssl-connection, and failed, because of a

    ssl_generate_keyring_material not enough data to generate key (0x17
required 0x37 or 0x57) 

Although the cause was a misconfiguration in the apache webserver, it seems
also a problem with wireshark, not being able to handle fragmented
ssl-handshakes.

As proposed in
http://www.wireshark.org/lists/wireshark-users/200903/msg00047.html I open a
bug report for it.

Find the cap-file enclosed. Unfortunatelly I cannot provide the private key,
because it is in productive use.
