Still problem here.

Please try this:

0. Put attached 2 files into ~
1. `emacs -Q ~/minimal.el'
2. Adjust path to org-mode git dir and Eval Buffer minimal.el
3. Try 'C-c a a'
-> It fails for me
4. Uncomment `org-agenda-add-time-grid-maybe' in minimal.el
5. Eval Buffer
6. Try `C-c a a'
-> It works for me

If you do it not today, reschedule item1 in test.org to $today.
