This happens when there are multiple PDFs embedded in a single PDF file.
I remember reading a Ghostscript bug about this (could probably find it
again if I had the exact error message), but unfortunately Mupdf still
doesn't support it.
Here is the Ghostscript bug:

From here it looks like you might be able to get it with gs after all.
Good research Anthony. That bug describes my situation exactly. The only
thing is that I didn't know what the hell a portfolio PDF was until now.
Unfortunately, the gs ports is version 8.63 (released 2008-08-01). This
bug report/fix happened in April 2009.
Shit, now Mr. Schroder is going to be on my ass about patches again. :-P
