A single packet that will crash Wireshark in the ieee80211 dissector.

Build Information:
SVN 40006

Load the attached .pcap file.  Wireshark will crash.  This bug was discovered
while fuzzing the menagerie for testing my recent changes in packet-ip.c;
however, the crash is occurring in a completely different place, namely in
packet-ieee80211.c.   Here's the call stack:
