CollectEvents throws errors since upgrading to ArcGIS 10 SP3

I have been running a Python script derived from a ModelBuilder model for a few years without a problem.  Since upgrading to ArcGIS 10 SP3 from just ArcGIS 10 I now get the following error:

Traceback (most recent call last):
  File "C:\Python26\ArcGIS10.0\CL00 CL Script.py", line 1252, in <module>
ExecuteError: <type 'exceptions.AttributeError'>: DescribeData: Get attribute extent does not exist
Failed to execute (CollectEvents).

It seems to be part of the CollectEvents internal script, since I do not have any call to DescribeData in my script.  The CL_INTERSECTION_ENDS_Layer's underlying feature class and layer are generated in the script.  I have not upgraded the script to use arcpy, so it still uses the old gp processor.  I have isolated the script portion that starts with CollectEvents (it is in the middle of the original script) and run it from that point without an error.  Any ideas on what I need to do to get this error to stop interupting my script?
