I've tried your patch, and it works great!.

The problem is that I want to maintain both systems (maps and topo) and I have to change URI prefix and directory of maps every time. I am working in which it can be two different definitions for URI/directory (maps and topo) and we could exchange easily among them. I hope to have something for tomorrow (it depends how fast i can learn to programme in maemo ) . I already have something, but it crash when change each other for two times.

Greetings. Demostenes.

PS: Thanks for your explanation about atof and setlocale. I had no idea.
