[O] "empty" CATEGORY lines behaviour

[Dieter Faulbaum]

I found that the version 7.7 of org-mode behaves differently than the
older version (which I got from http://emacs.naquadah.org/unstable/) some
version before. 


I have special lines in my org file like this (to remind me to go later
to work.-):
 
#+CATEGORY: shift
* <2011-07-04 Mo 12:00-20:30>

The 'org-agenda-list' from the "old" org-mode version showed this line
like this:

   shift:      12:00-20:30

But in the newer version I get only this warning:

Args out of range:   shift:    12:00-20:30 , 0, 10243

If I add any char before the date, it works again but that's not what I
want. I like the old behaviour.

Is this a (new, wanted) feature or a bug?
