Working and non-working PDFs

PDF images that I generate using the PDF::API2 Perl library do not convert to JPG using the ImageMagick convert command when the PDF uses OpenType (otf) fonts.  However, the process works fine when using TrueType (ttf) fonts.  The only difference in the creation of the two files is whether TTF fonts or OTF fonts are being used; all calls and other code used to create the files are identical.

Two example PDFs, one that works and one that does not work, are attached.

To connect this report more specifically to Ghostscript, note that the non-working file cannot be opened with the 'gs' command in X11.  The file opens, but before the text is displayed, the command errors out.  As you might expect, the file that does work does open fine using the same gs command in X11.  The non-working PDF does open fine in all other programs, such as Acrobat, Preview, PDFPen Pro and others, both on the machine that created the PDF and other machines.

This failure of the convert command has been tested on both RHEL and Mac OS X (Snow Leopard) platforms.

Using TrueType fonts, the command works fine:

[ 02:23 PM (352) continuum:thoth ~ ] > convert working.pdf working.jpg 
[ 02:23 PM (353) continuum:thoth ~ ] > ls working.jpg 
working.jpg

But when using OpenType fonts, the command fails as follows:
