Hi,

Steps to reproduce:
1) In an empty org-mode buffer, type a * SPC a C-b C-b C-b <RET>.
2) The buffer now has two lines, the first one "a" and the second "* a".
Expected:
3) The second line is formatted as a first-level heading.
Actual:
3) The second line is formatted as normal text.
Thanks for the report, I can confirm this bug with latest org.
Here's a patch that fixes this.
Regards,

Subject: [PATCH] org.el (org-fontify-extend-region): Fix headline
fontification in edge case
* lisp/org.el (org-fontify-extend-region): Fix fontification of
headline or meta line created by inserting a newline.
Unrelated to the fix: `org-fontify-extend-region' is added to
`font-lock-extend-after-change-region-function' and doesn't need to
use `save-excursion'.
