[Qgis-user] Error with the plugin contour with Qgis 1.8.0 on mountain lion

[niandra1982]

Hi all

I  installed the plug in contour (with a lot of work) but when i try to use
it i have this message:
Exception struck: 24879,

then it write the following

Errore durante l'esecuzione di codice Python:
(this is in italian, maybe in english is something like "errore during
Python execution")
