[O] Bug: Invalid hline refernce + org-edit-special freeze emacs [8.2.10 (8.2.10-29-g89a0ac-elpa @ /home/artis/.emacs.d/elpa/org-20141222/)]

[Artis Rozentāls]

A reference to a non-existant hline as the formula target results in a
complete freeze when running org-edit-special (and moving the cursor
down if invoked via C-c ') despite performing seemingly correct calculations.

An example of such a table is attached.
