Kim, probably you have a special character in your module/Option (such
as á, à , ã or something). Right?
Because I'm using Ubuntu 9.10 and I have already coded a NDVI function,
very similar to yours, and it's working just fine. as soon as I put a
character like those, I get an error like
*(python:3562): Pango-CRITICAL **: pango_layout_get_cursor_pos:
assertion `index >= 0 && index <= layout->length' failed*
and huge wxPython GUI error in command window.

Yeah sure...
The following was printed in TERMINAL:

`WIDGET_REALIZED_FOR_EVENT (widget, event)' failed
And at the command output it was:

This gives us any light?

Can you post the output from "i.ndvi --interface-description" ?
