When at home I get the following error in org-mode when bringing up the Agenda: Wrong type argument: stringp, nil I don't get this error on my setup at work. I am using org 4.77 (reports as 4.76) with GNU Emacs 22.1.50.1 (i686-pc-linux-gnu, GTK+ Version 2.10.11) of 2007-06-09. This version of Emacs came from the Gentoo masked ebuild so there may be some issues with it. For the M-x toggle-debug-on-error backtrace see the attached file. -- Rick rick.moynihan@gmail.com
