Thanks Jaap. From http://library.gnome.org/devel/glib/2.12/glib-running.html, I
found that if I set G_DEBUG=fatal_criticals that tshark will abort at the first
occurrence.
With that set, I ran tshark in gdb and got the backtrace, which follows. I've
been trying to figure out what's going wrong, stepping through the code in gdb,
but haven't been able to draw any conclusions yet.
