gpx export and location

[Lojze Blatnik]

Hi

We noticed interesting behavior regarding exporting gpx. On ubuntu 20.04
gpx export doesn't produce correct location. Docker recipe (see Dockerfile
and entrypoint.sh):
https://github.com/DZRJL/build/tree/211a227a8da5b4e0c2d76e9b50ddfdfd770faa27

Interestingly, on ubuntu 18.04 it works correctly, but survexport doesn't
come with the distro, hence extracting the deb package and hacking the
missing library :)
This works correctly:
https://github.com/DZRJL/build/tree/9c8de8ebabc5121f74c76ebbf63d4a84a5372da7

In the attachment .3d and .gpx for both cases.

Best regards,
