[Qgis-user] Intersect results in empty geometry

[simbamangu]

I (and another GIS.se user) have been trying to intersect lines and polygons
in 1.8.0-2 (OSX 10.7.4) as well as the 2.0-dev without success,  getting
empty geometries
<http://gis.stackexchange.com/questions/36934/is-there-a-way-to-split-a-polygon-layer-with-a-line-layer>  
(but no errors listed);  this worked fine in 1.7
<http://gis.stackexchange.com/questions/25357/divide-a-complex-shape-file-into-a-grid> 
.

*I looked at a  recent related thread
<http://osgeo-org.1560.n6.nabble.com/Trouble-with-overlay-in-1-8-0-td4998524.html>  
but it seems to relate to an issue with points.
*There is also a  possibly related bug listed as 'closed'
<http://hub.qgis.org/issues/5861>   four months ago.
*The empty geometry problem happens with both the built-in Vector menu
(fTools) as well as with SEXTANTE.

Any way to fix this, or are we waiting for a future build?
