Run ulimit -a and see if you have core files set to 0 or unlimited.

You want to run gdb against the core and run bt full for a full backtrace and include that along with the logs for your report.

$ gdb application core.Xorg

gdb> bt full

Send this & logs in the bug report.

ulimit -a gives me:
core file size          (blocks, -c) 0

Other than that, I do not understand your instructions... For my case where the 'application' crashing is the Xserver, how will I run gdb on it?

You need to enable core files.

In a console:
1. ulimit -c unlimited
2. then reproduce the problem in that console (it should generate a core file)
3. find / -type f | grep -i core  (it is normally in the directory where you run the program)
4. gdb /usr/bin/Xorg /path/to/core
5. bt full
6. Send that in a bug report.
