--
tshark segfaults when it runs Lua scripts that contain Lua GUI functions
(http://wiki.wireshark.org/LuaAPI/GUI).

To reproduce, run the following sh command:

$ echo TextWindow.new\(\) > /tmp/test.lua && ./tshark -v
-Xlua_script:/tmp/test.lua

** (process:63647): WARNING **: openSAFETY - SercosIII heuristic dissector
cannot be registered, openSAFETY/SercosIII native dissection.
Segmentation fault


Note that the segfault occurs for several other Lua GUI functions, including
`ProgDlg.new()` and `new_dialog()`.
