I found a bit more information. First, I had only turned on DEBUG logging for the root category (non-DSpace code). This morning I also enabled DEBUG logging for logger.org.dspace as well, and found confirmation that the media filter is running the "pdftoppm" command and producing output.
The problem seems to be occurring in the call to "ImageIO.read(outf)". From the online documentation for the javax.imageio package for Java Platform SE 6, the "*read*" function: Returns a BufferedImage as the result of decoding a supplied InputStream with an ImageReader chosen automatically from among those currently registered. The InputStream is wrapped in an ImageInputStream. *If no registered ImageReader claims to be able to read the resulting stream, null is returned.* This is most likely the problem. Any ideas why there would be no registered ImageReader for a PPM input stream?
