Upgrade to Wireshark 1.2.1 or later.

If are running Wireshark 1.2.0 or earlier (including Ethereal) and cannot upgrade, you can work around each of the problems listed above by doing the following:

  • Disable the affected dissectors:
    • Select Analyze→Enabled Protocols... from the menu.
    • Make sure "AFS (RX)", "Infiniband", "IPMI/ATCA", "L2CAP", "MIOP", "RADIUS", and "sFlow" are all un-checked.
    • Click "Save", then click "OK".
