[Qgis-developer] Contour plugin (Official QGIS repository) failure

[G.T.C.vandenBerg]

Hello,


I had planned to use the QGIS-plugin 'Contour' from the Official QGIS repo
to create a contourline-shapefile from a point-shapefile. My point-shapefile
has 1 column ('z') in which represents the altitude of the points. However,
when I click the plugin-button I get the following message:


"Failure while executing Pyton code:

Traceback (most recent call last):
File "/home/guus/.qgis//python/plugins/contour/contour.py", line 266, in
uFieldNameUpdate
x, y, z = self.getData(self._layer, inputField)
File "/home/guus/.qgis//python/plugins/contour/contour.py", line 590, in
getData
z = map(float, z) #TODO : take care of NaNs, NULL, "",...
ValueError: could not convert string to float:

And when I close this message, I get another one:


"Failure while executing Pyton code:

Does anybody have an idea what goes wrong? It's clearly not my
point-shapefile, as the failure-message appears before I'm able to select
anything.
