当我进入议程视图并尝试按标记过滤（C-c a t / TAB PC RET）时，我一直收到以下错误：
org-tags-expand: Wrong type argument: listp, #("{\\<\\(?:pc\\(?:desktop\\|mobile\\)?\\)\\>}" 0 36 (grouptag t))
这是标记在同一文件中的定义方式：
#+TAGS: { PC : PCDesktop PCMobile }
我在OS X Yosemite上使用Emacs Version 24.4（9.0）。组织模式版本是
Org-mode version 8.3beta (release_8.3beta-669-g077a24 @ /Applications/Emacs.app/Contents/Resources/lisp/org/)
我尝试使用稳定版本，然后更新到测试版，我仍然遇到同样的问题。我在设置的任何组标签中遇到此问题。当我创建自定义议程命令时也会发生这种情况。
以下是我的.emacs文件：
;; -*- mode: lisp -*-
;; Disable the splash screen (to enable it agin, replace the t with 0)
(setq inhibit-splash-screen t)
(set-face-attribute 'default nil :height 120)
;; Enable transient mark mode
(transient-mark-mode 1)
;;;;org-mode configuration
;; Enable org-mode
(require 'org)
;;(setq org-todo-keywords
;; '((sequence "TODO" "IN-PROGRESS" "WAITING" "DONE")))
;; The following lines are always needed. Choose your own keys.
;; (add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode)) ; not needed since Emacs 22.2
;; (add-hook 'org-mode-hook 'turn-on-font-lock) ; not needed when global-font-lock-mode is on
(global-set-key "\C-cl" 'org-store-link)
(global-set-key "\C-ca" 'org-agenda)
(global-set-key "\C-cb" 'org-iswitchb)
;; Make org-mode work with files ending in .org
;; (add-to-list 'auto-mode-alist '("\\.org$" . org-mode))
;; The above is the default in recent emacsen
(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.

我确保org-group-tags设置为不为零。任何帮助将不胜感激。
