marble failing tests for KDE Applicationst 15.12 release

[Albert Astals Cid]

Hi Aleix can you please comment on the marble failing tests

https://build.kde.org/user/aacid/my-views/view/KDE%20Applications%2015.12/job/marble%20Applications-15.12%20stable-kf5-qt5/PLATFORM=Linux,compiler=gcc/lastCompletedBuild/testReport/

Tagging is just 2 days away so we need to fix them ASAP or have a good reason 
of why we want to ship with these failing tests.

Cheers,
  Albert
