Package: w3m-el
Version: 1.2-1
Severity: normal

Same as Subject.
The erro does not depend on the gnome feature.  

 A backtrace is:
 	Signaling: (wrong-type-argument stringp nil)
	string-match("^[ -~]+$" nil)
	(if (string-match "^[ -~]+$" (symbol-value ...)) (symbol-value (quote w3m-current-title)) (directory-file-name (if ... ... ...)))
	(let* ((len ...) (name ...) (num ...) (lnum ...)) (setq ad-return-value (if num ... ...)))
	(if (and w3m-xmas-show-current-title-in-buffer-tab (symbol-value ...) (eq ... major-mode)) (let* (... ... ... ...) (setq ad-return-value ...)) (setq ad-return-value (ad-Orig-format-buffers-tab-line buffer)))
        (save-current-buffer (set-buffer buffer) (if (and w3m-xmas-show-current-title-in-buffer-tab ... ...) (let* ... ...) (setq ad-return-value ...)))
        (with-current-buffer buffer (if (and w3m-xmas-show-current-title-in-buffer-tab ... ...) (let* ... ...) (setq ad-return-value ...)))
        (let (ad-return-value) (with-current-buffer buffer (if ... ... ...)) ad-return-value)
