Thats supposed to be an error condition exit only.
Isnt there a return statement before?

I havent yet tried to recreate your problem, but my experience when I
worked on the patch was that I got memory issues when working with image
bundle files.

Also the imagemagick team was very helpful in providing fixes in their
code.

Have you tried to install a development version of imagemagick?
