I uncovered this error when testing ArcMap 10 SP2 for a customer:

This occurs when the conflict is detected--ArcMap is attempting to show the conflicts window but fails.
I get this error on all workstations at the customer's location (all Windows XP). But I don't get the error on my systems (I've tried XP and Windows 7).
I've tried various oracle/sql server combinations and I still receive the error on the customer's workstation.
It appears to be a compatibility issue and I have an open Esri incident which hasn't yielded any results, so I thought I'd tap the gis.se.
Has anyone experienced this error with this set(or similar set) of conditions?
Update From Comments: I initially got this in an Oracle10/9.3.1 sde database, but also replicated the error with a sqlexpress/arcsde 10. I only have this issue with the customer's ArcGIS Desktop workstations and each experience the same issue.

New Information (8/4)
Client is getting this in ArcGIS 9.3.1 as well--they so seldom get conflicts that this hasn't been an issue until now.
I'm nearly certain that this issue is caused by some other software that was pushed out to these machines. We're still troubleshooting and I'll update this question with an answer once I know more.
