FOP give image error on some systems (linux, windows so far)
When adding image (png) output from the R actor, we were getting odd image IO errors from the Apache-FOP classes. It's not every image and not on all platforms. Before going to Kruger, we saw it on my Ubuntu machine, Jing's linux (I believe Ubuntu), and then on Judith's Windows XP machine (that was the surprise!)
It does not seem to happen in OS X at this point.
