[gdal-dev] what does "Ring Self-intersection at or near point" really mean ?

Hi everyone

I'm generally getting a lot of

GDAL warning: 1 : Ring Self-intersection at or near point 382104

when importing shapefiles that are assumed to be of good quality. I dont see
these kind of errors when importing into ArcCatalog. This also leads to
OGRGeometry not being valid.

Anyone knows what's behind this ?
