Resolution

Upgrade to Wireshark 1.0.1 or later.

If are running Wireshark 1.0.0 or earlier (including Ethereal 0.99.0 or earlier) and cannot upgrade, you can work around each of the problems listed above by doing the following:

• Disable the GSM SMS, PANA, KISMET, RTMPT, and RMI dissectors:
  • Select Analyze→Enabled Protocols... from the menu.
  • Make sure "GSM SMS," "PANA," "Kismet," "RTMPT," and "RMI" are un-checked.
  • Click "Save", then click "OK".
