Title
"Object not set to a reference of an object" when simulating sync project. -
Description
The issue is intermittent and can not be reliably reproduced. An error like this will be seen :

Cause
In some cases unexpected NULL list elements can be generated in the code, which causes the report to crash. -
Resolution
Defect #37279 has been logged for this. It is planned for inclusion in the 9.2 release.
