Hello Carsten, when I clock in/out from the agenda (using I/O) the function 'org-format-agenda-item' is called with a non-nil 'noprefix' argument. This leads to an error because the variable 'thecategory' is nil in line 4610 of file org-agenda.el.
I would supply a patch if I understood the meaning of the 'noprefix' flag. Thanks, Stephan Emacs : GNU Emacs 22.3.1 (i686-pc-linux-gnu, GTK+ Version 2.16.6) of 2009-10-06 Package: Org-mode version 6.31trans (release_6.31.35.g7ce8) _______________________________________________ Emacs-orgmode mailing list Remember: use `Reply All' to send replies to the list.
