[Paraview] Paraview crashes on .vtu file load

[Alice Gabriel]

Dear Paraview-user and developers,

Paraview crashes immediately once I try to load ascii .vtu files I 
self-wrote with a small python wrapper.
No error messages are parsed and I am lost in finding the reason for the 
crash.

An example .vtu file causing the crash I uploaded here:
https://dl.dropboxusercontent.com/u/12694118/sample_unstruct_tet.vtu

Thank you very much,
Alice Gabriel

Here the python wrapper:

[...]

fo.write('<VTKFile type=\'UnstructuredGrid\' version=\'0.1\' 
byte_order=\'BigEndian\'>\n')
fo.write('<UnstructuredGrid>\n')
fo.write('<Piece NumberOfPoints=\'' + str(npts) + '\' NumberOfCells=\'' 
+  str(nelem) + '\'>\n')
fo.write('<Points>\n')
fo.write('<DataArray type=\'Float64\' NumberOfComponents=\'3\' 
Format=\'ascii\'>\n')

for i in range(npts):
     fo.write('   ' + str('{: .16E}'.format(data[0,i])) + '   ' + 
str('{: .16E}'.format(data[1,i])) + '   ' + str('{: 
.16E}'.format(data[2,i])) + '\n')

fo.write('</DataArray>\n')
fo.write('</Points>\n')
fo.write('<Cells>\n')
fo.write('<DataArray type=\'Int32\' Name=\'connectivity\' 
Format=\'ascii\'>\n')

for i in range(nelem):
      fo.write(' ' + str('{:6d}'.format(elems[0,i])) + ' ' +

fo.write('</DataArray>\n')
fo.write('<DataArray type=\'Int32\' Name=\'offsets\' Format=\'ascii\'>\n')

for i in range(nelem):
     fo.write(' ' + str('{:6d}'.format((i+1)*4)) + '\n')

fo.write('</DataArray>\n')
fo.write('<DataArray type=\'UInt8\' Name=\'types\' Format=\'ascii\'>\n')

for i in range(nelem):
     fo.write(' ' + str('{:6d}'.format(10)) + '\n')

fo.write('</DataArray>\n')
fo.write('</Cells>\n')

fo.write('<CellData Scalars=\'scalars\'>\n')

for j, var in enumerate(vars[3:]):

     fo.write('<DataArray type=\'Float64\' Name=\'' + var + '\'

     for i in range(npts):
         fo.write('   ' + str('{: .16E}'.format(data[j+3,i])) + '\n')

     fo.write('</DataArray>\n')


fo.write('</CellData>\n')
fo.write('</Piece>\n')
fo.write('</UnstructuredGrid>\n')
fo.write('</VTKFile>\n')
fo.close()
