[Zope] Weird ZCatalog problem... bug?

[sean.upton@uniontrib.com]

On my developmet box, I'm using Zope 2.2.1 and ZCatalog to index
ZClass-based classified ad objects; for some reason on sort="title" in the
<dtml-in Catalog ... I get inconsistent results.  I perform a search and get
incorrect results.  I then click refresh, get results sorted differently,
then click refresh again, and it's messed up again.  Anyone seen anything
like this?  Thoughts?

Other info about setup:
Globbing vocabulary
Catalog and indexed objects are in BTree folder
ZClasses catalog aware
Other sort= values seem to work.

Here is a DTML snippet...
<dtml-var expr="REQUEST.get('fieldsort')">
<dtml-in Catalog size=50 start=query_start sort="REQUEST['fieldsort']">
...
</dtml-in>

URL looks like
results?title=&AdBody=par*&WeightWords=&fieldsort=title&SUBMIT=Submit+Query

Thanks,
Sean
