306 The thing near the bottom of the buffer is how the environment
307 settings will be included in the mail. Please do not delete that.
308 They will tell the Bug People what your environment is, so that it
309 will be easier to locate the bugs.

312 debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
313 and include the backtrace in your bug report.
