It may or may not be relevant, but this PDF file is damaged. Although created
9th January 2009, it was modified on 17th February 2009, I would suspect the
edit of having caused the damage.

Opening the file with Acrobat briefly displays a warning before displaying the
page, and when you close the file asks if you want to 'save the changes'.

Ghsostcript gives a warning that the xref table is damaged, then 24 warnings
about stream lengths being incorrect, and finally 24 errors reading content streams.

It does however display all the pages without causing a crash. Possibly MuPDF is
using an older version of JasPer, or possibly the problem is caused by the
damaged xref/content streams.

Works with OpenJPEG.
