Description
1) add a point layer with a reasonable density of points in QGIS with SEXTANTE plugin
2) perform a "Thin Plate Spline (global)" (under SAGA - "Grid - Spline" with all the default settings
On Ubuntu 11.10 and Win7 with QGis 1.8.0 and SEXTANTE 1.0.7, this results in error similar to this (taken from sextante_qgis.log):

could you add the points layer you are using? I have just run that algorithm with a point layer and I had no problems. If the problem is with large layers or with many points, then it might be a saga problem, so I would like to check that. Thanks in advance.

- File 24-05-2012_12_NO2.txt.zip added
see attached delimited text layer (in EPSG:31370). This is indeed a large file (ca. 400k points), but I also tried it with a smaller subset (ca 20k points), same result.
