SetHeaderAndFooterText throws an exception

Hi,

When I set the footer- and header-text with SetHeaderAndFooterText I am receiving an exception:

Editor.Document.SetHeaderAndFooterText("script{ $text = \"", "\"; }");

Object reference not set to an instance of an object.

at ActiproSoftware.Text.Implementation.TextDocumentBase.SetHeaderAndFooterText(String headerText, String footerText)
at IamConsole.View.WorkflowDocument.TextDataItemView.OnInitialized(EventArgs e)

After inspecting the header and footer afterwards, the header and footer appear to have the correct values:

((ActiproSoftware.Text.Implementation.TextDocumentBase)(Editor.Document)).CurrentSnapshot.HeaderText == "script{ $text = \""

Simply ignoring the exception seems to work for me, but I would like to prevent this from happening.
