Set variable `debug-on-error' to t. 2. Provoke the error, so you can see which function is problematic. Quit the debugger using `q'. 3. Load the source files for the package in question. This is to give you a more human-readable backtrace. 4. Provoke the error again. You can now report the problem to the package maintainer. If the responsible code is delivered as part of Emacs (not some 3rd party) then report the problem to Emacs Dev using `M-x report-emacs-bug'. If you want to debug it further yourself, step through the debugger after step #4 above. Use `d' to single-step and `c' to skip through a step. Use `q' to quit or step through until the problematic function returns. Some people prefer `edebug' to `debug'. I prefer `debug', which is what you get with the above recipe.
