[Zope] Weird problem with ZDebug

[Andrew Templin]

I'm currently running Zope 2.3.3 on a Debian potato system (ia32), using 
the default Python 1.5.2 install from Debian potato.  I've built the Zope
system by hand and had no problems.  Apache sits in front of the Zope
system using the normal rewrite rules for Zope.

The problem I'm running into is that I can't seem to get ZDebug 
(version 0.2.1) to do ... well, anything useful.  I'm using 0.2.1 because
0.3 only works with Zope 2.4 and above.

The test_html DTML document is as follows:

--- begin ---
<dtml-var standard_html_header>
<dtml-var blah>
<dtml-var standard_html_footer>
--- end ---

The property "blah" does not exist in an attempt to cause an exception.

Instead of getting the ZDebug page that I expect, I instead get the 
standard_error_message page along with this traceback:

<!--

Ok, this works fine at my employers - however, at work I have python 2.x 
(2.0, if memory serves me) and Zope 2.3.3.  Do I need to upgrade my potato 
system to python 2.0?

Any help appreciated.
