Alternatively, or perhaps as well, extract the information with a core. There are some excellent instructions on generating some comprehensive crash reports here: http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kernel= debug.html This looks like it's a NULL pointer dereference, so the question we need to answer is: which pointer? To do that, we'll need to turn that back into a C line number, which will need the kernel with debugging symbols. Thanks!
