[Qgis-user] Why does this message keeps occuring in QGIS? GEOS geoprocessing error: One or more input features have invalid geometry.

[Kirk Schmidt]

This usually occurs when you try to merge features that are mixed single 
and multipart lines or polygons. Simply use vector geometry tools to 
convert from one type to another.
