[Zope-PTK] Strange error with search

[Nolan Darilek]

I've managed to create a cool event registering/calendaring system,
and am really starting to appreciate Zope's power! :)

I'm running into yet another strange problem, though. I've begun
adding events into our calendar. The events appear on the news pages
as they should. I can also search for a few keywords and receive
results.

I've created an event, however, which causes a traceback when I search
for the word 'spring'. The error is:

|Zope|Zope Error                                            |
|    |                                                      |
|    |Zope has encountered an error while publishing this   |
|    |resource.                                             |

|    |Error Value: not all arguments converted              |
|    |------------------------------------------------------|

The traceback is:

Traceback (innermost last):

Can anyone suggest what that might mean? I can search for the word
'spring' and cause the error, but searching for 'oscar' works
nicely. The site is at http://donna.muq.org:9673/brackroberts/ if
anyone wants to test different searches.

Thanks.
