The following command will core dump. (It also core dumps when a capture file
is used instead of /dev/null. This is just an easy way to demonstrate the
problem.)
tshark -V -T ps -i - < /dev/null
%!
%!PS-Adobe-2.0

(a bunch of PostScript)
%% the page title
Bus error
The error does not occur with -T text, -T psml, or -T pdml.
The problem was reproduced using the official download of 1.2.10 from
wireshark.org. However, it also occurs in our built-from-source version 1.2.4
on darwin and linux. The 1.2.4 backtrace is:
Program received signal SIGSEGV, Segmentation fault.
