[Bug 2058415] [NEW] Reading binary date broken by libexpat1 update

[Carsten Gräser]

Public bug reported:

The recent update of libexpat1 to version 2.5.0-2ubuntu0.1 broke Paraview. 
In particular reading vtu files containing binary data fails since this update. When trying to open files that worked fine before, Paraview now reports a parsing error like this one:

ERROR: In vtkXMLParser.cxx, line 376
vtkXMLDataParser (0x5b0ac36fc970): Error parsing XML in stream at line 21, column 0, byte index 1036: not well-formed (invalid token)

ERROR: In vtkXMLReader.cxx, line 521
vtkXMLUnstructuredGridReader (0x5b0ac3d3b670): Error parsing input file.  ReadXMLInformation aborting.

The problem disappears when reverting libexpat1 to version 2.5.0-2.
