[Solved] Shift Selection causes error

[Inquisitor Jax]

When I select an item, then hold shift and select a second item, I get an exception:
"Specified argument was out of range of valid values"

Call stack:
>    Telerik.Windows.Data!Telerik.Windows.Data.QueryableCollectionView.GetItemAt(int index = -1) + 0x76 bytes    
     Telerik.Windows.Data!Telerik.Windows.Data.Selection.SelectionHandler.MultiSelect(object actionItem) + 0xdf bytes

PS: It only occurs in the internal builds that are available (happens with 2_911 & 2_925)
It works fine with 2_812 release.
