I did a lot of testing with different zone outlines and found out that if I place a zone cut out area 5 x 5 mill at a specific place on the board the zone fills as expected. I can't see anything wrong with that particular area on the board and the zone fill command gives no error messages.

The library used to do polygon calculations (kbool) in zones fails in 
very rare cases.
(in fact i saw this problem in debug phase of new zone calculations, but 
never in the stable version).
Fortunately, when happens, a very small change in zone parameters solves 
the problem.
In your case, after removing the little zone cutout (when kbool fails), 
if you change the zone clearance from 0.381 to 0.386 (for instance) the 
problem disappears.
