querying a broken polygon crashes QGIS

[msieczka]

SVN 7389.

When querying or editing a broken "polygon" (consisting of only 1 or 2 vertices) in a shapefile (created in fGIS) QGIS crashes as following:

Debug: /home/shoofi/src/straight/qgis09/src/core/qgsgeometry.cpp: 3303: (exportWkbToGeos) Polygon found
terminate called after throwing an instance of 'geos::IllegalArgumentException*'

Program received signal SIGABRT, Aborted.

The shapefile is attached. The polygon in question is the sliver to the very west.
