wow, libgarmin is chatty.
Couple of suggestions:
1. Use navit.pastebin.com to provide a link to data such as this.
2. Generally speaking, maps don't display unless you either have a GPS lock (which you don't in your trace) or the center.txt file has coordinates that are within your active map. Center.txt accepts various formats.
3. Join #navit via IRC, let them know the pastebin link. There should be more help there on libgarmin issues
