This bug report will be sent to the Bug-GNU-Emacs mailing list and the GNU bug tracker at debbugs.gnu.org. Please check that the From: line contains a valid email address. After a delay of up to one day, you should receive an acknowledgment at that address. Please write in English if possible, as the Emacs maintainers usually do not have translators for other languages. Please describe exactly what actions triggered the bug, and the precise symptoms of the bug. If you can, give a recipe starting from `emacs -Q': Emacs reports this error: Invalid time specification whenever I execute woman. For example m-x woman hostname (invoke woman to view the hostname man page). This error occurs in: Debugger entered--Lisp error: (error "Invalid time specification") float-time(0.04446005821228027) woman-decode-buffer() woman-process-buffer() woman-really-find-file("/usr/share/man/man1/gzip.1.gz" t "*WoMan 1 gzip*<3>") woman-find-file("/usr/share/man/man1/gzip.1.gz") woman(nil nil) call-interactively(woman record nil) command-execute(woman record) execute-extended-command(nil "woman") call-interactively(execute-extended-command nil nil) The code in question is in woman.el (woman-decode-buffer): (defun woman-decode-buffer () "Decode a buffer in UN*X man-page source format. No external programs are used." (interactive) ; mainly for testing (WoMan-log-begin) (run-hooks 'woman-pre-format-hook) (and (boundp 'font-lock-mode) font-lock-mode (font-lock-mode -1)) ;; (fundamental-mode) (let ((start-time (current-time)) time) (message "WoMan formatting buffer...") ; (goto-char (point-min)) ; (cond ; ((re-search-forward "^\\.[ \t]*TH" nil t) ; wrong format if not found? ; (beginning-of-line) ; (delete-region (point-min) (point))) ; potentially dangerous! ; (t (message "WARNING: .TH request not found -- not man-page format?")))

The float-time function gags on this. A corrected version omits float-time: (setq time (time-since start-time)) If Emacs crashed, and you have the Emacs process in the gdb debugger, please include the output from the following gdb commands: `bt full' and `xbacktrace'.
