Several users have reported receiving this error from Adobe Acrobat when opening (some?) faxes. While other readers appear to display the contents correctly in these cases there is clearly something wrong with the contents. I have several examples of these broken pdfs and will post here when I've solved the problem.
Meanwhile, if you end up with a fax that you need and can't open with Adobe, try using Foxit or another reader in its place.
