[Paraview] syntax error in smtrace.py

[Jean Favre]

python gives me the following syntax error on all the systems I have
with python version less than 2.5, and python tracing is thus not
working on these systems.

Compiling
/workspace/jfavre/ParaView3Build/Utilities/VTKPythonWrapping/paraview/smtrace.py
...
 File
"/workspace/jfavre/ParaView3Build/Utilities/VTKPythonWrapping/paraview/smtrace.py",
line 6
   class trace_globals(): pass
                       ^
SyntaxError: invalid syntax

Any workarounds?

TIA
