Hmmm...I get it, too. I should I say I "got" it, because after I
started investigating the problem I started getting other very odd
errors and then it started working. Now I can't make it happen anymore.
These are classic symptoms of a wild pointer either in RMagick or
ImageMagick. I'll poke around a little bit more. Whatever the problem
is, it can't be fixed by changing the script.

Thanks for pointing this out.
