Newbye: segfault when loading ROOT libraries in ipython

Hi,

I want to use pyroot to access routines in a library developed for ROOT.
This library requires loading other (standard ROOT) libraries.
In ROOT, I can load all those libs with no problem:

root [1] gSystem->Load(“libPhysics.so”);
root [2] gSystem->Load(“libFFTW.so”);
root [3] gSystem->Load(“libHtml.so”);
root [4] gSystem->Load(“libTreeViewer.so”);
root [5] gSystem->Load("/home/guest/WAT/tools/install/lib/wavelet.so");

However, in ipython with pyROOT module, I get the following segfault
and ipython crashes. Any ideas of what I’m doing wrong?
I provide the trace at the end of the message.

ipython
Python 2.7.3 (default, Mar 13 2014, 11:03:55)

In [1]: import ROOT
In [2]: ROOT.gSystem.Load("/usr/lib/libPhysics.so")

*** glibc detected *** /usr/bin/python: double free or corruption (!prev): 0x0000000001659870 ***

Thanks,
Eric
