When performing M-x diredp-do-bookmark on a selected file from a dired buffer, (keybinding M-b) the minibuffer correctly prompts, "Bookmark ? (y or n). However, when answering `y', it responds: Failed to create bookmark for `': Wrong number of arguments: #[(name alist no-overwrite) "\306 \210\307^H!^Y\310\311 G\312 $\210\204#^@\313 \314\"\203#^@\313 !^K\241\210\202)^@ ^KB^LB^T ^U^N^PT^V^P\315 \2038^@\316 \210 ^U\317 )\207" [name stripped-name no-overwrite alist bookmark-alist bookmark-current-bookmark bookmark-maybe-load-default-file copy-sequence set-text-properties 0 nil bookmark-get-bookmark noerror bookmark-time-to-save-p bookmark-save bookmark-bmenu-surreptitiously-rebuild-list bookmark-alist-modification-count] 5 ("/usr/share/emacs/24.4/lisp/bookmark.elc" . 16242)], 4 This reproduces consistently. The files tested had `simple' filenames (only [a-zA-Z] characters, no whitespace in filenames) in my home directory. The source of the error seems to be in function `diredp-bookmark' in file dired+.el. There (my line #6102), a call to function `bookkmark-store' includes an extra parameter no-msg-p. When I removed that parameter, the function did work. A secondary problem may be why function `diredp-bookmark' has parameter no-msg-p in the first place. A second secondary problem may be why the funky error message. A third secondary problem may be that `diredp-do-bookmark' doesn't prompt the user for a bookmark, and just assumes that the user wants the bookmark-name to be the filename. Personally, my preference / vote would be to have a user prompt, with the minibuffer pre-filled with the filename. A final issue is that the function includes a comment, "NEED to keep this code sync'd with `bmkp-make-record-for-target-file'.", but I can't find such a function.
