Getting-ArgumentException-Destination-array-was-not-long-enough-since-B128

Hello together,

since I updated WL to Build 128, 129, 130, 131 and 132 I receive many of this Exceptions:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
System.ArgumentException: Destination array was not long enough. Check the destination index, length, and the array's lower bounds. (Parameter 'destinationArray')
at System.Array.CopyImpl(Array sourceArray, Int32 sourceIndex, Array destinationArray, Int32 destinationIndex, Int32 length, Boolean reliable)
at System.Array.Copy(Array sourceArray, Int32 sourceIndex, Array destinationArray, Int32 destinationIndex, Int32 length)
at System.Collections.Generic.List`1.CopyTo(T[] array, Int32 arrayIndex)
at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection)
at WealthLab.WPF.DataSetTreeView.ConnectReponse(TreeNode res, DataSetProviderBase cont)
at WealthLab.WPF.DataSetTreeView.<>c__DisplayClass27_0.CustomizeVisitor()
at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)
at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Until Build 130, it was only at my LIVE System, but now it also started at my Development System. Can someone help me to find out the reason? Unfortunately, the Exception don't has any further informationen about strategy or DataSet.

Regards
Oliver
