[Zope] KeyError since installing Squishdot 0.4.0

[David Trudgett]

Since I installed Squishdot 0.4.0 (yesterday) on Zope 2.1.6 (under Red Hat 
Linux) I've been getting KeyErrors when clicking on an article's topic 
image, which uses an URL like this:

http://myserver/Zope/testsquish/search?subject=Squishdot&op=articles

In Squishdot 0.3.2, the errors didn't occur.

I applied the fixes mentioned by Michel Pelletier in his (Zope-dev] message 
("The Mysterious Key Error and Unrelated Searc Result Bug"), and updated 
the ZCatalog. This didn't fix the problem.

Here is the stack trace:

Traceback (innermost last):

Does anyone have any ideas on how to fix this?

Thanks.
