[Zope-Coders] type(s) crashes Python 2.1.1 in PyObject_Print

[Andreas Jung]

While writing a C extension for Python 2.1.1 I noticed that
'print type(s)' inside PyObject_Print; however "a=type(s)" works
and "print a" crashes Python. This problem occurs also with
some extension modules of Zope e.g.

import ZopeSplitter
s=ZopeSplitter.ZopeSplitter("Python rocks")
print type(s)

crashes:

Is this a problem of Python or is there something in the C extension missing
?
