Imagemagick PDF to JPG conversion failing

I'm trying to convert the first page of a PDF to a JPG. I'm pretty sure I got this to work with certain PDFs, but is it really possible that certain PDFs are made incorrectly and cannot be converted?

I tried running this first:

$ convert 10-03-26.pdf[1] test.jpg

And I got the follow:

Error: /syntaxerror in readxref
Operand stack:

Execution stack:
   %interp_exit   .runexec2   --nostringval--   --nostringval--   --nostringval--   2   %stopped_push   --nostringval--   --nostringval--   --nostringval--   false   1   %stopped_push   1   3   %oparray_pop   1   3   %oparray_pop   --nostringval--   --nostringval--   --nostringval--   --nostringval--   --nostringval--   --nostringval--

Current allocation mode is local
ESP Ghostscript 7.07.1: Unrecoverable error, exit code 1
convert: Postscript delegate failed `10-03-26.pdf'.

Running this instead:

$ convert -verbose -colorspace rgb '10-03-26.pdf[1]' test.jpg

I get the following:

Why would the conversion fail?

Thanks!
