With any PDF plugins disabled, attempt to download the PDF http://www.alfresco.com/services/subscription/supported-platforms/3-x.pdf, or browse to http://www.alfresco.com/services/subscription/supported-platforms/ and click the link Supported Platforms for Alfresco Enterprise 3.x.

The download dialog displays:
PDF Document (-1 bytes)

The other PDFs on http://www.alfresco.com/services/subscription/supported-platforms/ work fine.

I noticed that the server does not appear to be sending a Content-Length header for the problematic file.

Why is this a core bug?  Core is correctly reporting a content-length of -1 (which means unknown).  Sounds to me like the UI is what's broken.

Probably worth a tiny comment here to note that .contentLength == -1 when the length is unknown.
