[TJ <ubuntu@xxxxxxxxxxx>]

I've now got a much fuller back-trace from gdb since installing the
Python debug symbols (libpython2.6-dbgsym, python2.6-minimal-dbgsym)
from the Debug archive (see
https://wiki.ubuntu.com/DebuggingProgramCrash)

I've not had chance to review this yet but I thought I'd share it in
case something stands out to someone else.
