Comment 10 for bug 238572

Below are the headers for Firefox 2 when it tries to display the pdf file. Saving the file always works. It is only when we have the acrobat reader plug-in on our browser that it has problems with the documents out of the document library.

When opening:
http://documents.beds.ac.uk/dl/training/handle/3736129497719782140/uob-archiving-gw.pdf
we get a 'stopped' message at the bottom of the browser and the headers look like this.
