I think I've tracked it down to swig 1.3.30rc1.  This didn't have the correct 
#if statement for Py_ssize_t as of PEP 353.  It's fixed correctly in 1.3.30 
and 1.3.31.  

The combination that failed was:

swig 1.3.30rc1 + Python 2.4.4 + M2Crypto 0.18.2

Python 2.5 works fine regardless of swig version.

For the record the distros I used were Redhat Enterprise and Ubuntu:
