RadGridView problem with 2011 Q2 hotfix

[Lucie]

after using 01648RadControls_for_Silverlight4_2011_2_1107_DEV_hotfix.zip we got error
Line: 51
Error: Unhandled Error in Silverlight 2 Application
Code: 4004   
Category: ParserError      
Message: Set property 'System.Windows.FrameworkElement.Style' threw an exception.    
File:     
Line: 95    
Position: 25    

We cannot find file where is problem. Have you somewhere in repository description of changes for this hotfix?
What can be reason for ParserError in Set property?
The same error happen for 2011 Q3.
