Quite strange/unusual...
ImageMagick 6.2.4.5 which you say is the latest in Debian is more than 2
years old. Any chance you could chase them up to see whats going on there?
Here is a patch which switches to older APIs which should be available
in your version. Does it help?
Thanks,
Daniel

Subject: [PATCH] Use older ImageMagick API
Debian ship an ImageMagick that is more than 2 years old. Switch to using
older APIs so that we have compatibility all-round.
