Hey,

Thank you for your report.

It is a known issue: Unity Issue Tracker - [Linux Editor] Crash in funlockfile (Material::UnshareMaterialData()) when unloading a scene
Could you try checking out if the issue still persists for you in the newest build? You can download it here: http://beta.unity3d.com/download/7807bc63c3ab/public_download.html

sure,
am i going to re download every unity component again ?
or can i just merge it with the old installation ?

You should re-download everything, since it’s a new version.
