[GRASS-dev] Re: Scripting in Linux (Kim Besson)

[António Rocha]

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.
