emacs25-dbg (if exists in Raspbian) is needed for readable stack traces.

If you have emacs25-src installed, you have the source, I suppose.

Okay, after installing emacs25-dbg, do this:

$ gdb emacs
(gdb) run
<... use emacs until it crashes ...>
(gdb) backtrace
(gdb) xbacktrace

Copy the output of the last two commands and paste them on the buffer
created by M-x report-emacs-bug.

To exit GDB:

(gdb) quit
