Ar-code attachment_fu

I've run into some problems with temp files using RMagick after updating Ruby to 1.8.7. The result is that attachment_fu is creating the thumbnail images, but they're the same size, resolution, and dimensions as the original - in other words, the image isn't getting processed. I get the following errors:

This prevents all of the image processing I do using RMagick, including a script that I use to render text on images. Any thoughts on this?

Thanks,
