OSD Results (applications tab) filled with Unknown packages

Environment is ConfigMgr 2007 R3. I've done the MDT 2012 integration and am using an MDT UDI task sequence to deploy Windows 7 SP1 x64. There is nothing wrong with the actual deployment, just a cosmetic issue with the Applications tab of the OSD Results screen.

I'm not sure if it is related, but the only error I found in my task sequence was with the 'Parse Base Variable' step of the 'OSD Results and Branding' phase. Here is an extract from smsts.log:

This seems to indicate that the object was never set, but after looking at the code it does appear to be set. This error can be matched up with the GetBaseVariableName function in OSD_BaseVariables.vbs.

'from main'
Dim oTSE

'from SetObjects function'
SET oTSE = CreateObject("Microsoft.SMS.TSEnvironment")

'from GetBaseVariableName function'
oTSE( TsSaveVarName ) = TsBaseValue
oTSE( TsAppsVarName ) = TsAppsBaseValue
If (Err.Number <> 0) Then 
	GetBaseVariableName = false
	wscript.echo " --| Error: [" & Err.Number & "]"
	wscript.echo " --| Description: [" & Err.Description & "]"
End If

Anyone have any idea why this would be happening? The other option is to turn the application tab off in the OSD Results screen, but I do not see a way to do that.

Thanks!
