It works fine on the slightly old

Org-mode version 7.9.3d (release_7.9.3d-826-gbe0d87.dirty @ /home/nick/elisp/org-mode/lisp/)

with the following file as the only agenda file:

--8<---------------cut here---------------start------------->8---
# timestamp: <2013-01-24 Thu>

* TODO foo
  SCHEDULED: <2013-01-24 Thu>
--8<---------------cut here---------------end--------------->8---

If I get rid of the # or add something else before it, I get the
message you mention, but otherwise it is silent.

Assuming you are running a more recent version than the one above,
the bug may be because of a recent change to org-agenda-skip:
it used to check explicitly for # and skip the entry, but commit
211b137ef46d04b17b46f256696eb5c1c3a1d2be changed it to check a text
property. I guess the text property is not present or it is not checked
correctly.
