alternatively, to not be blind about other maybe serious warnings/errors: http://alxr.usatlas.bnl.gov/lxr/source/atlas/Tools/PyUtils/python/Helpers.py?v=head#015 which can be used like so:

with Helpers.ShutUp():

   f = ROOT.TFile.Open(fname)

the class captures stdout and stderr, apply some regexp-filtering on those and print whatever does not pass the filter(s)

the default filters are:

   DefaultFilter = [

       re.compile("Warning in <TClass::TClass>: no dictionary for class."),
       re.compile("Warning in <TEnvRec::ChangeValue>: duplicate entry."),
       re.compile("Error in <TStreamerInfo::BuildOld>:."),
       ]
