Error of Layout WPF

I have this SurfaceListBox:

<my:SurfaceListBox Margin="10" x:Name="grid1" VirtualizingStackPanel.IsVirtualizing="True" Style="{DynamicResource SurfaceListBoxStyle1}" ItemContainerStyle="{DynamicResource SurfaceListBoxItemStyle1}"
								  VirtualizingStackPanel.VirtualizationMode="Standard"  VirtualizingPanel.ScrollUnit="Pixel"  my:SurfaceScrollViewer.CanContentScroll="True">

which I add like items several UserControl. Theese UserControl in their Loaded methods loads many TextBlock that change their position after an UserControl maximize.

The problem is when I maximize and minimize many times it shows the following error:

"Layout measurement override of element 'System.Windows.Controls.TextBlock' should not return PositiveInfinity as its DesiredSize, even if Infinity is passed in as available size."

Somebody knows how resolve it? Thanks.
