I just did an upgrade from the previous build and I noticed the following issue
which I have not seen before:

[Dissector bug, protocol TCP:
C:\buildbot\wireshark\wireshark-2.0-64\win7x64\build\epan\dissectors\packet-tcp.c:1969:
failed assertion "mptcpd != ((void *)0)"]
    [Expert Info (Error/Malformed):
C:\buildbot\wireshark\wireshark-2.0-64\win7x64\build\epan\dissectors\packet-tcp.c:1969:
failed assertion "mptcpd != ((void *)0)"]
       
[C:\buildbot\wireshark\wireshark-2.0-64\win7x64\build\epan\dissectors\packet-tcp.c:1969:
failed assertion "mptcpd != ((void *)0)"]
        [Severity level: Error]
        [Group: Malformed]

This seems to apply to each and every TCP packet in each capture file I have.
