Imagemagick, Snow Leopard, and PDF Conversion
Difficulties with Imagemagick and Snow Leopard.
Imagemagick was installed using an install script here here . Everything builds and installs correctly. Imagemagick behaves fine for all commands (which I can find) except when trying to convert PDF. For example,
$ convert my.pdf my.jpg
Segmetation Fault
I thought it might be ghostscript and tried to run the command which Imagegick delegate too (via the -verbose option)
$ convert -verbose spec/fixtures/documents/upload_test_file.pdf test.jpg
"gs" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pnmraw" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" "-sOutputFile=/var/folders/Xz/Xz6TDr0DFQaV5J1F7Ndamk+++TM/-Tmp-/magick-4zvJXfSz" "-f/var/folders/Xz/Xz6TDr0DFQaV5J1F7Ndamk+++TM/-Tmp-/magick-O7a9fDyp" "-f/var/folders/Xz/Xz6TDr0DFQaV5J1F7Ndamk+++TM/-Tmp-/magick-rBEzLUsx"

$ "gs" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pnmraw" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" "-sOutputFile=my.jpg" "-fmy.pdf"
And it works. It creates the pnmrow file as intended.
I'm not sure where to go from here, has anyone else seen this or seen it and solved it?

me too.
$ identify issue7.pdf

It looks like the imagemagick team is aware of the problem and it should be fixed in version 6.5.5-8.
UPDATE: Actually - the MacPorts package uses a newer version of ImageMagick from 9/16/09. Try to self-update and then update php5-imagick.
sudo port selfupdate
sudo port upgrade php5-imagick
This fixed the problem for me.
