Problem instrumenting defuns for debugging when running speedbar

Hi When trying to call Instrument This Defun For Debugging from the right mouse popup-menu inside of a lisp file I get the following messages and stacktrace when running speedbar in another frame. This happens only when trying for the first time. From then on I can succesfully instrument: Loading edebug... Loading edebug...done Symbol's value as variable is void: speedbar-with-writable Signaling: (void-variable speedbar-with-writable) #<compiled-function nil "...(5)" [def-body speedbar-with-writable def-edebug-spec] 3>() run-hooks(#<compiled-function nil "...(5)" [def-body speedbar-with-writable def-edebug-spec] 3>) edebug-read-and-maybe-wrap-form() edebug-read-top-level-form() #<compiled-function nil "...(10)" [eval t edebug-all-defs edebug-all-forms edebug-read-top-level-form] 3 ("/usr/local/lib/xemacs/xemacs-packages/lisp/edebug/edebug.elc" . 13819) nil>() call-interactively(edebug-defun) menu-call-at-event(edebug-defun) eval((menu-call-at-event (quote edebug-defun))) dispatch-event(#<misc-user-event (eval (menu-call-at-event (quote edebug-defun)))>) popup-mode-menu(#<buttondown-event button3>) call-interactively(popup-mode-menu) Any idea ??
