ftools: mean coordinate tool returns error when used on spatialite vector

[lutra]

Tested on qgis trunk, Ubuntu 9.10 and with the spatialite sample dataset.

With he same vector (regions) saved as shapefile the tool works ok.

An error has occured while executing Python code:

Traceback (most recent call last):
  File "/usr/share/qgis/python/plugins/fTools/tools/doMeanCoords.py", line 62, in accept
    self.compute(inName, outPath, self.weightField.currentText(), self.sizeValue.value(), self.uniqueField.currentText())
  File "/usr/share/qgis/python/plugins/fTools/tools/doMeanCoords.py", line 150, in compute
    cx = cx / sumWeight
ZeroDivisionError: float division

Python version:
2.6.4 (r264:75706, Dec  7 2009, 19:02:09) 
[GCC 4.4.1]

Can't reproduce with my data. Can you attach a sample and explain all actions to get this error?

Hi,

Now I cannot test again with a more recent code, but then I:

*) used the spatialite sample dataset (you find it in the SL site)

*) tested the "regions" layer with the "mean coordinate" tool available in the "vector" menu

Can't reproduce with SpatiaLite? sample data and with my own spatialite data. Reopen if necessary
