For problems with packages that are not part of Emacs, it is better
to begin by reporting them to the package developers.

@cindex dribble file
@cindex logging keystrokes
One way to record the input to Emacs precisely is to write a dribble
file. To start the file, use the @kbd{M-x open-dribble-file
@key{RET}} command. From then on, Emacs copies all your input to the
specified dribble file until the Emacs process is killed. Be aware
that sensitive information (such as passwords) may end up recorded in

@cindex backtrace for bug reports
For example, many people send just a backtrace, but that is not very
useful by itself. A simple backtrace with arguments often conveys
little about what is happening inside GNU Emacs, because most of the
arguments listed in the backtrace are pointers to Lisp objects. The
numeric values of these pointers have no significance whatever; all that
matters is the contents of the objects they point to (and most of the
contents are themselves pointers).
