Q:

Export from Org Mode to LaTeX doesn't accept the option #+title:

When I try an export from Org Mode to LaTeX I get the following error message:

apply: Wrong type argument: listp, #("Aufgabe 3" 0 9 (:parent (#0)))

The problem comes from the option 

#+title: title.

I don't have any special settings for LaTeX-Export.
Where does this error message come from?

A:

Way too late of course. Well, I had the same problem with the AUTHOR header, and found a solution.
C-u M-x org-reload solved my problem.
