This appears if the system folder is formatted case sensitive. By moving /Applications/igotu2gpx.app/Contents/Frameworks/ to /Applications/igotu2gpx.app/Contents/FrameWorks/ (i.e. Frameworks -> FrameWorks) you can download the tracks. Unfortunately some paths related to marble are looked for in Frameworks so the mapping wont work. I solved this by running
on the terminal in /Applications/igotu2gpx.app/

find . -type f -exec perl -p -i -e 's/FrameWorks/ Frameworks/ g' {} \;
That will replace in all files FrameWorks with Frameworks and igotugui works fine again.
