Description
Writing a python plugin for QGIS, I use the function unaryUnion to obtain correct lines to be used in polygonize function. The function works correctly with some layers (layer PolygonToLineLayer0-limited1.shp), but it doesn't work with another layer (PolygonToLineLayer0-limited3.shp). And I don't find what could be the problem, just think that unaryUnion doesn't work in a specific case.
You'll find attached my 2 layers and an extract of my python code.
