[O] if: Wrong type argument: stringp, \.\.\.

[Markus Heller]

Hello group,

I'm stumped.  When I try to bring up the agenda with C-c a, I get the
error message mentioned in the subject line.

I'm using 23.2.1 on Windoze 7 64 bit, and the orgmode from today:

M-x org-version: 7.5

Here's my entire org-mode related part of my .emacs:

,----

Any hints are highly appreciated.
