It seems the issue is similar to bug#560215.  I was not able to reopen the last bug so I have opened a new one. I am using an external python extension which seems to be buggy. I am still investigating the actual cause of the bug in the said extension library.

PyType_IsSubType segfault reason is NULL pointer derefrence @ PyType_IsSubtype (a=0x0, b=0xb7f1ea00)
attaching the gdb bt as attachment.

I don't think this is a bug in the core. Most Python API functions may not be passed NULL pointers;
it is expected that the user of the function checks for that condition.
