In this case it should be enough to install the debug packages and not use NoTrapSignals, because then the backtrace should appear in Xorg.0.log (like the one you posted in the tarball). Anyway thanks for the notice about /var/lib/gdm3/core, the documentation should probably be updated.

This looks similar to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=649231 and https://bugs.freedesktop.org/show_bug.cgi?id=43893 so I will reassign the bug to libdrm.
