External http link not recognized as link

Question

I have the following document:

* Test
| Links |
|-------|
| [[http://emacs.stackexchange.com/questions/ask]] |

This Link is not recognized as a Link. If I press TAB while the cursor is on the link the cursor moves to the beginning of the line and I get a warning in messages:

font-lock-fontify-keywords-region: Wrong type argument: listp, org-table

If I remove http from the link, it works. If I change http to some other term like httpd it works also. It just seems, http and https do not work.

What am I doing wrong? What is missing? How can I add a external http link to an org table?
