That also has some other information on formatting submissions. Please think hard before including complete backtraces in upstream reports, they are very large and contain almost no useful information relative to their size so often obscure the relevant content in your message. If part of the backtrace is usefully illustrative then it's usually better to pull out the relevant sections. --MrRUTeZlqqNo1jQ9 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl37qDQACgkQJNaLcl1U h9AJaAf/VcHw+FsWnYuqSH2qZ99vzwAVGSKy0z4tlu31qUpDCG9ck7/2ZIjbLjfC 9oJH30f+UFJ+8FbtWqkjqlQKlWfEsvJb1u6t3/MT2id0izMJhZmNEL2rejzJN9mJ er+nAY71b7qSiGFeZIJ4WfDisQ5PN13Bb8Jc89xX81/AhXeeWQD+nzSim1oTkC51 nL6yv7348KLjmfxjWh/RDRpMGjnB36NqDElOS5JFleqrBj5VpYGgCaPAAYHiUByO fRk//M+nrGRqaYxQ6ux4KQjsnMURsAiI1eC1FsZ+qR6WBXFIyiWy2DfF7YnnWGuO XxFimsqORIFr+lhUPeBOxQjQ4XHnVw== =Xr2v -----END PGP SIGNATURE----- --MrRUTeZlqqNo1jQ9--
