This issue happened because we are in a headless environnement. check this: https://github.com/vtkiorg/vtki/issues/155

Solution for this can be used xvfb but with simple test, it doesn't work as expected. I get : 

XIO:  fatal IO error 0 (Success) on X server ":2123779251"
      after 55 requests (55 known processed) with 0 events remaining.

in Tracim using patched code https://github.com/algoo/preview-generator/tree/fix/163__fix_x_issue_with_vtk , this also close directly Tracim process which is not nice at all. Seems that something is not properly close.
