Resolution
Upgrade to Wireshark 0.99.5.

If are running Wireshark 0.99.4 or 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 HTTP, IEEE 802.11, and LLT dissectors.
      o Select Analyze→Enabled Protocols... from the menu.
      o Make sure "HTTP", "IEEE 802.11", and "LLT" are un-checked.
      o Click "Save", then click "OK".
