This issue is still affecting me. I've upgraded the server to run ImageMagic 6.4.9 with newer librsvg2, and it now renders PNG files, without a crash or error. I've purged the thumbnails for the relevant images so we don't have old image files in the system.
However I still have the same problem that SVG files are not included in the PDFs produced, but PNG files are. If I upload the PNG thumbnail rendered on the server as an image in it's own right and use that on the page, then that image is included in the PDF. So the PNGs that the server produces can be read by PIL. Full of mw-render is attached. I'm not quite sure why texvc and blahtexml aren't found, because they are installed in /usr/local/bin - maybe that isn't in the apache user's PATH, although I'm not very clear where that is set up or how to change it. There is still the fatal entry 2009-03-11T12:28:23 rlwriter.warning >> img can not be opened by PIL Looking at the URLs retreived, it is definitely the SVG file which is being got from the server, not the rendered PNG version. Would it be useful to make the render server keep the zip file and see exactly what images got downloaded into it?
