There are two files in xemacs-packages/etc/sounds that will crash xemacs. They are really text files, but they are named like sound files which tempts the user into playing them and crashing their xemacs. Maybe they should be renamed to README.wav.txt and README.au.txt? Lisp backtrace follows: play-sound-file("/usr/local/lib/xemacs/xemacs-packages/etc/sounds/README.au") eval((play-sound-file "/usr/local/lib/xemacs/xemacs-packages/etc/sounds/README.au")) # bind (expr) eval-interactive((play-sound-file "/usr/local/lib/xemacs/xemacs-packages/etc/sounds/README.au")) # bind (standard-output opoint ignore-quotes eval-last-sexp-arg-internal) eval-last-sexp(t) # bind (standard-output) #<compiled-function nil "...(13)" [standard-output terpri eval-last-sexp t] 2 1019499 nil>() call-interactively(eval-print-last-sexp) # (condition-case ... . error) # (catch top-level ...)
