The exception is thrown in RadDocument.IsInNonEditableRange() method, which is called before measuring the document. When using a format provider, the error is thrown but the document can still be opened in RichTextBox. In binding scenario, the document is not imported.

Workaround: Ensure the document is measured before assigning it to RadRichTextBox.

Release LIB 2019.3.1216 (12/16/2019)
When trying to import a document containing bookmark and BookmarkRangeEnd is after the last paragraph, a StackOverflowException is thrown in IntervalNode while trying to rebuild the document cache. (RadDocumentChildrenCache.RebuildTree()).

The same could be observed if the bookmark end is last in the header/footer, between table cells in the RadDocument body, or when all paragraphs after the bookmark range end are hidden (with vanish property).

Workaround: Detect the problematic annotations and remove them:
foreach (var rangeStart in document.EnumerateChildrenOfType<AnnotationRangeStart>())
{
    if (rangeStart.End == null || rangeStart.End.Parent == null || rangeStart.End.Parent.Parent == null)
    {
        //MessageBox.Show("This indicates a problem.");
        rangeStart.Parent.Children.Remove(rangeStart);
    }
}

Note: Until 2017 R2 SP1 release StackOverflowException is thrown, after this release an ArgumentException should be thrown.

Release 2019.3.1209 (12/09/2019)
There is a NullReferenceException thrown while trying to compare positions for restoring them after pasting the document. The exception is handled but after it is thrown, the layout stops updating.

Workaround: Ensure the document is not empty before pasting content inside:
private void RadRichTextBox_CommandExecuting(object sender, Telerik.Windows.Documents.RichTextBoxCommands.CommandExecutingEventArgs e)
{
    if (e.Command is PasteCommand && this.radRichTextBox.Document.IsEmpty)
    {
        this.radRichTextBox.Insert(" ");
    }
}

In this example, the current synchronization context is "occupied" by the task that sets the RTF string forcing the arrange tasks to wait for it to complete before they can start. However, it can never complete as it is blocked by the wait call for the arrange tasks that will never run, causing a deadlock.
