Using Visual Studio 2008 and .NET 3.5SP1. Using an evaluation license.

In a new WPF application I create a new UserControl named MyControl. From the SampleApplication I copy the contents of ProgrammaticCreation.MainWindow into the UserControl, both xaml and cs. Any references to MainWindow are replaced by MyControl.

Now when I take certain steps I always get an exception in my own project, but I can not reproduce it in the sample application. There are various ways to reproduce it, this is one of them:

1. Press the Create button twice. Tool Window 1 (TW1) and Tool Window 2 (TW2) are created.
2. Move TW2 and dock it at TW1
3. Move TW2 again, this time dock it at the original ToolWindows, "Original Tool Window" and "Another Tool Window".

Most ways to reproduce this seem to involve moving one or multiple windows around at least 2 or 3 times.

It always results in the same exception:

Ah, apologies. I still had a URI reference to an image from the sample project. Replacing that by null fixed the problem. Strange that it doesn't crash the first time it tries to display the image though. It takes a couple of moves before it crashes.
The latest build of this product (v2019.1 build 0683) was released 1 month ago, which was after the last post in this thread.
