Scotese's shapefiles causes Tethys to crash

[asierra]

Qgis 1.5.0 crashes everytime I try to load a shapefile from the Earth System History GIS collection from C. R. Scotese ( ​http://www.scotese.com/ ). The same files loaded fine with previous versions of Qgis. If necessary I can send sample shape files to developers. Below is a report from console:

please attach sample data

Sample shape files that make qgis crash in snow leopard

[lutra]

it is confirmed, the shapefile is pretty "dirty", you can confirm by importing it in GRASS and you'll see a lot of slivers and ovrlapped polygons. Nevertheless QGIS should not crash.

Message is

ERROR 1: Corrupted .shp file : shape 182 : panPartStart[2] = 114, nVertices = 114
Segmentation fault

[pcav]

Is this still true for qgis 1.6? Which GEOS version?

[aghisla]

It is true for QGIS trunk, r15304. QGIS crashes with the error signaled by lutra.

most likely a duplicate of #2837 (upstream bug already fixed in GDAL 1.7.3)
