[Zope] ZCatalog raises index out of range exception error

[Martin Winkler]

Hi listies,

On a client's server I created a ZCatalog, but when using "Find Items to 
ZCatalog" and clicking on "Find" in the form, Zope raises the "list index 
out of range" error shown in detail at the end of this e-mail. Then I took 
the whole Data.fs, put it on one of our servers, where everything worked as 
usual.

Since our client wants to create various ZCatalogs, he has to use this 
functionality :-/

Any ideas where to start looking for the reason of this error?

Our client's server's configuration is the following:
Zope version: Zope 2.2.4 (source release, python 1.5.2, linux2) [ I have 
also tried with 2.2.2 source]
Python version: 1.5.2 (#1, Aug 25 2000, 09:33:37) [GCC 2.96 20000731 
(experimental)]
System Platform: linux-i386 [RedHat 7.0]

Any help is greatly appreciated!

Martin
