Problem loading a PDF, annotating it and saving it to PDF

I've been playing around with the ImageMagick PHP extension, Imagick, and I ran into a problem. I was trying to create an image by pull some PDFs in as images, add some text, then save the file to a new PDF. I don't get any problems creating the file, but when I tried to open the PDF with various programs, I got these results:
With Evince (Gnome document reader), it loads fine.
With acroread, I get "There was an error processing a page. There was a problem reading this document (14)."
With gs, I get "Error: /typecheck in --run--"
Eventually I was able to recreate the problem on the command line with a single command:
convert multipage.pdf -annotate 0x0+30+30 text out.pdf
The resulting PDF file exhibits the same problems I was having with Imagick. Interestingly, removing the -annotate portion results in a functioning PDF file. On a hunch, I removed my annotation calls in my PHP script and the PDF started working as well. Another interesting was that I'm able to convert the PDF, with annotation, to a PNM file, and then convert the PNM file to a PDF without a problem.
I've tried installing various versions of ImageMagick (6.2.4, 6.3.7-8, 6.3.7-9, 6.3.7-10, and svn) but all of them have the same problem.

Post a URL to your multipage.pdf file so we can download it and reproduce the problem. When we used our own multipage PDF file with your command, we got a valid out.pdf file.

I'm going to feel very dumb if it was just the PDF file I was testing.

UPDATE: I tried
http://www.irs.gov/pub/irs-pdf/fw2.pdf as well and got a broken PDF.

We tried your image with ImageMagick 6.3.8-0 Beta and it converted fine and produced valid PDF output. 6.3.8-0 Beta is scheduled for release within a week or two.

Is that version in your Subversion repository somewhere? I compiled revision 9100 from trunk this morning and it's what I've been doing all my tests against for the later half of this day.

Is there something else that might be causing this problem on my system? Maybe some dependency that I may have overlooked? I know that the version of ImageMagick in Ubuntu's repositories is ancient (6.2.4 or something). GhostScript seems up to date, so I'm not sure could be out of date.

The subversion trunk is ImageMagick 6.3.8-0 Beta. We're using Ghostscript 8.61. Not sure why you are having problems. We tried you PDF and command on 5 different OS's and could not reproduce the problem.

I've confirmed that the problem occurs on two different Ubuntu 7.10 machines as well as a Debian machine (not sure what version it is though). I also confirmed that it works on a FreeBSD virtual machine, so it would seem to be something Debian-based.
