[Gvsig_english] Geoprocessing tools::strange error appears when trying to clip, intersect, ...

[Wolfgang Qual]

Hi list,
I would like to test the geoprocessing-functions of gvSIG. However, Clip and 
Intersect did not work correctly by now. I always get the same error message: 
Result layer is empty. Check for possible error.
I do not really understand this, as - within the view - it is clear to see 
that there are overlapping areas, therefore, I would expect a result for clip 
or intersect in this case.

Is there a known bug in version 1.0.1 (running on Linux, Debian).

Comments are appreciated!

Best regards,
Wolfgang
