With a wslua dissector Wireshark crashes with segmentation fault.

How to reproduce:
1. Save the attached test_dissector.lua
2. Save the attached test.pcap
3. Enable wslua by commenting out the "disable_lua ..." line in init.lua
4. Add the 'dofile("/path/to/test_dissector.lua")' line at the end of the
init.lua script
5. Start Wireshark with "wireshark test.pcap"

Current result:
Wireshark chrashes most of the time with segmentation fault.

Expected result:
Wireshark starts; loads and displays the test.pcap
