The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  tcpdump                                  3.9.4-2ubuntu0.2

Ubuntu 6.10:
  tcpdump                                  3.9.4-4ubuntu0.2

Ubuntu 7.04:
  tcpdump                                  3.9.5-2ubuntu1
