When opening a capture file with a failed SSL handshake, wireshark does not
mark the packet as SSL or show the Client Hello information.

When cutting the capture file short (so not including the failing part) the SSL
information is displayed successfully.

I have included 2 capture files to show the problem.

session.full_anon.pcap: packet 4 should be the Client Hello, but it doesn't
dissect it properly.

session.part_anon.pcap: packet 4 show correctly.


I've tried to anonymize the files as much as possible. Please treat them as
confidential.
