Bug Description
PcbNew Build: (after 2015-mar-04 ) running on 64-bit Windows 7
I have two overlapping filled zones. The reason for two is that need to have thermal reliefs on all of my pads but there is one pad with thermal vias where I don' want thermals. So I add a polygon in the middle of one big GND polygon with no thermals. The corners of this polygon don't mesh properly with the rest of the GND pour. This technique is also helpful when you need different clearances in different areas of the board. See picture attached.

The issue is caused by the zone filling algorithm taking the outline of of the higher priority zone instead of its actual contents (filleted corners create 'kinks' seen on the image)
