This is kinda new, so i guess something went wrong when updating, but now I get this:

I think I updated QT implicitly when I last updated cmake, are the versions somehow incompatible? In any case a segmentation fault seems wrong to me.

after reinstalling everything it seems to work now. Plus vlc also crashed in the same qt5 function, so something must have been wron with my qt5 installation.
