Wireshark-dev: [Wireshark-dev] repeatable crash in tshark, but can't reproduce standalone

This isn't critical for us, and I haven't been able to reproduce it by
running tshark standalone, and its an old tshark version... but I
thought I'd report this in case anybody knows what's going on.

We run tshark from inside a python/twisted exe, that's running as
root. If I run from the command line, then ctrl-C/SIGINT, tshark
crashes, every time.

I don't think it crashes with my local build from svn.

Anyhow, this is what we get:
