[Paraview] Error opening specific STL-files on specific computer ("unable to read point")

Hi everyone,

I've been using Paraview for a couple of years now and it's been great. However, I've now encountered a weird problem that I cannot solve. A couple of years ago, I used VTK (and Python) to automatically segment the skin layer surface out of MRI scans. I've always been able to view the resulting surface meshes in Paraview and other 3D visualization programs such as Meshlab. 

I would now like to work with this dataset again, but I cannot get the surfaces -which are stored as STL-files- to open on my computer. When I try to open them in Paraview (I've tried both 4.1.0 and 5.0.1), I get the following error:


ERROR: In /home/kitware/dashboards/buildbot/paraview-debian6dash-linux-shared-release_opengl2_qt4_superbuild/build/paraview/src/paraview/VTK/IO/Geometry/vtkSTLReader.cxx, line 461

When I try to open them in Meshlab, I get an error message about "Premature End of file". Other STL-files, however, do open. I'm working on Ubuntu 15.10 64-bit. At first I assumed that the STL-files had somehow all gotten corrupted, but they open perfectly on a colleague's computer (Paraview 5.0.0 running on OpenSuse) and on my Windows 8.1 laptop (both in Paraview 5.0.0 and in Meshlab 1.3.3).

I'm not sure what's wrong. Could anybody please offer some insight? 

I've attached an example file to this e-mail.

Kind regards,

Daniel
