Hi Carsten and the Orgers, I had this mode line entry now since I created that example file for lists two (?) days ago. As I accidentally removed the clocking information by hand, the clock was gone. Somehow, I was clocked out anyway (`C-c C-x C-o'), but the modeline string remained. No matter how hard I tried - I only got the error message. This patch removes the clock-entry from the modeline, if (not org-clocking-p).
