I had a similar problem few weeks ago. Without going into details
I tried a "brute force" approach adding to x and y geographical
coordinates small random parts (about 0.0001 * coordinate value).
Error disappeared and the resulting contour plot was OK.
But it does not of course explain the reason for the peculiar
behavior of trigrid procedure...
