I encounted bug 325779 and was not able to restore it.  When I shut down and then opened the workspace with I20101026-0203 I got errors and the system didn't come up.

Comment 1 Remy Suen CLA 2010-10-26 09:40:15 EDT 
There are two problems here.

The first one is I only happened to wrap "half" the delta application attempts in a SafeRunner, so one failure has ended up causing all subsequent ones to not be applied (see bug 328709).

The second issue is that the EMS chokes on such a malformed model with placeholders not having a proper 'ref' target (see bug 328700).
Comment 2 Eric Moffatt CLA 2013-10-21 13:36:00 EDT 
We no longer use the 'deltas' approach...
