Access Violation when publishing this drawing to DWF

AutoCAD 2007 ADT A.54.0 (UNICODE)

I get an Access Violation at the "" stage when trying to publish one particular drawing file to DWF using the Publish feature, and the DWF radio button.

When I try to plot this particular drawing, and select the DWF55 or DWF6 ePlot drivers, the program hangs on the plot progress dialog.

Publishing or Plotting with a normal print driver, or a PDF driver, works just fine with this drawing.

What do you think could be in this drawing, that isn't in the other drawings, that could be causing this error?

Try shortening the name of the layout file.
