If part of the backtrace is usefully illustrative (it often is for search engines if nothing else) then it's usually better to pull out the relevant sections. --rmnoW3paj3umB6SM Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmIGTV4ACgkQJNaLcl1U h9C1KQf9GVPQqLpAYXPnTVXWv2GgFuiO3xWPa4fGn6NFNruqsC9kG0ILuIzo96nt Rt7bz7N2dqWB0CuQHZnyAPMmIe97An8dmUZkb1o4DzJVrQyQteZ1X6YQekbpvpSO kYS7IBZTqmQckxR0xKm9Wj9Sb6N+eZ3evbKgF+rGU1eIOeC0Qvaqd6QyNbddWEfB PuU4UpH42zkWR/tzrTM2sdZy82aylHomTEHRn1f+/bhOrPna9bn6PbV2nuJ5nOeN g4ARZsoRuFPYXn9dBvptd/YNinUyxuOLYgqyYl+r/XDgR7CPSH44s81EnsKNYO3N 9zmtydE+XHf6scVEtKuzSoilb26imw== =5FlO -----END PGP SIGNATURE----- --rmnoW3paj3umB6SM--
