Unity crashes on asset import

Whenever I try to import a 3D model into an empty project, the editor crashes. It does some of the importing, it at least copies the model files into the assets folder and the materials come through all right, but within the editor the models are treated as generic files, not as 3D data. I have tried .fbx and .dea models as well as downloading a package from the asset store, all with the same result. When I created a new project and included an asset package it crashed while creating the project. When I run Unity from a terminal, nothing is printed to it except "Aborted" right when Unity crashes. I'm using Linux Mint 17.2.

 

I have the same problem whenever I try importing assets it gets stuck on 83% please help me.
