[mkgmap-dev] BINGO -- Tile found??

Ups, I don't know what I was doing before, but now if I didn't somehow seriously harm my GPS -- it ain't booting at all if the only tile is: 63910066.img !!!! This tile contains only POI of type 0x11710 in resolution 24 Maybe if we have "3byte" POI, there must be place, or "2byte" -- 0x000?? -- POI? However if I add some other tiles to 0066 it will start. But this is the only tile if alone inside a gmapsupp.img, it will stop the device from booting. The big problem on that maptile is of course bad data -- but still it shouldn't crash the GPS device (and doesn't do if in the right combination with other maps..).
