[mod_python] Few lines of code that make my mod_python crash

Hi all,
 
Please, look at these few lines of code :
 
import shelve
 
def test(req):
        s=shelve.open('/tmp/test')
        return 'OK'
 
I have a Linux box with RedHat 3 AS, ActiveState Python 2.4.1,
Mod_python 3.1.4 (compiled with the --with-python option) (but I also
tried with python 2.4.1 from www.python.org <http://www.python.org/>  ,
compiled with BerkeleyDB 4.3 from sleepycat (also tried versione 4.2)
and with mod_python 3.1.4 compiled with the --with-python option).
 
The version of Apache is 2.0.46-25.ent 
 
If I try to execute these few lines from mod_python I get the error you
can see below (also tried with mod_python_servlets, same result, see
bottom of the message)
If I execute the same lines one at a time from the python interpreter or
If I run a script version of these lines from the bash prompt (e.g.
python scripttest.py) they work perfectly.
 
Any suggestion?
Thank you
