Neither way seems to be working for me now either, by the way... the
enigmail bunch keeps blaming the problems on "using unofficial builds of
thunderbird", but I don't really find that a fair excuse for an
architecture that isn't supported by the mozilla people. Obviously the
thing shouldn't be breaking here.

I'm getting SIGFPE too btw, not SIGSEGV.
