uploading .fit from Garmin Forerunner 165

[chri2]

I tried to upload files from a Garmin Forerunner 165 (previously copied to a directory on my disk).

The filename appears in the status line all at the bottom of the window, but there's no track shown in fittrackee-uploaders window.

In the terminal I started the program from there's no error message beside Gtk-Message: 14:55:02.562: Failed to load module "xapp-gtk3-module" directly after starting the program.
