[sword-devel] Python segfaults on OS X using Sword

I'm experimenting with the Python SWIG interface built from 1.5.10  
source on OS X 10.5.1. If I do things from the command line,  
interactively, all seems well. But if I run the following script, it  
segfaults Python with the following stack trace:

SCRIPT:

#!/usr/bin/python
import Sword
from Ft.Xml import InputSource, Sax

class element_counter:
     def startDocument(self):
         self.ecount = 0

     def startElementNS(self, name, qname, attribs):
         self.ecount += 1

parser = Sax.CreateParser()
handler = element_counter()
parser.setContentHandler(handler)

filtermgr = Sword.MarkupFilterMgr(Sword.FMT_OSIS)
mgr = Sword.SWMgr("/Users/jbrisbin/Library/sword/share/sword", True,  
filtermgr, True, False)
mod = mgr.getModule("ESV")
key = Sword.SWKey("Jn 3:16")
mod.setKey(key)

txt = '<?xml version="1.0"?>' + mod.RenderText()
print txt

factory = InputSource.DefaultFactory
isrc = factory.fromString(txt)
parser.parse(isrc)
print "Elements counted:", handler.ecount
