4suite and mod_python -- Import error when bringing in

[jsight]

Using a request.publisher style Request Handler...

Apache - 2.0.52
mod_python - 3.1.3

The code works fine outside of mod_python, but in mod_python, I get a "[Sun Feb 27 19:17:58 2005] [notice] child pid 17727 exit signal Segmentation fault (11)" error in the apache error_log.

Also, periodically, it will fail with an import error on the line:
from Ft.Xml.Xslt import Processor

The line:
from Ft.Xml import InputSource
works fine.

Also, removing all XSL makes the script work fine.

What could this problem be? All the mailing list posts that I have found basically say "Use the latest mod_python, expat, and 4suite as possible with Python 2.3". I am doing all of those, but still getting the segfault.

Any ideas?

Thanks for any help,
Jess

Here is the stacktrace from after I've gotten it into "Import fail" mode instead of "segfault" mode.

<a href="http://pyana.sourceforge.net/">Pyana</a> - I wish this had an ebuild in portage, but it's a Python interface to Xalan-C++. So far it seems pretty good, and possibly faster than the 4Suite XSLT implementation, anyway.

Works well under mod_python in my simple tests as well.

Anyway, hopefully someone else will fix the 4Suite and mod_python issues one day.
