InvalidOperationException: This Visual is not connected to a PresentationSource.

[thorstenhuy]

Describe the bug

Occasionally, we get an "InvalidOperationException: This Visual is not connected to a PresentationSource." which crashes the application.
This was already reported as issue #469. The proposed fix was to use the TryCatchOccurredException method.
The proposed fix does not work.
The reason for this is that the exception occurs in the Dispatcher thread of the DispatcherTimer of MouseHelper.cs (line 19). The ty/catch in DragDrop.DoDragSourceMove() will therefore not catch the exception, and the TryCatchOccurredException method is never called.
