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. --ixuD5kGB4Ce7Ycqb Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmgeqNsACgkQJNaLcl1U h9ALtAgAhqoLROAk68XqIAIUNwakSx5Hu9BxJ02NLgTZGWVExJnivI8g19E2t1UW oIwWu+532ZBP+Yoj2J9umF8bs10ztAJk7d3QhQyqZnR1lWYEw8RPesDJBQWz6/iP sgyr70mJ/x67QTyB1KDd7DYLyJwYvCYhO44uhB44ggCmWZif4Gy/bhseqGTlU6V1 G4gS0LeM5ycTdwnvFa3Otw/I+u9faB/AhgGzgZEQM36lEg5nRy0FFKHIlCEOmelm Sk5ql08Npgra2J0LmPTf0NSTA4BMj9+D5tIU7wnl95ZugOD1AvJFUKNguNiqpeEV 4Xar4GrEAWnBeiSjtReU+CO52H8c5g== =47Yh -----END PGP SIGNATURE----- --ixuD5kGB4Ce7Ycqb--
