Intermittent Failure: GraphicsMagic

Looks like it may have just timed out (2 seconds?). Maybe for tests this should increase.

I've uploaded the failure log masked as a JPG file (worth a try?). It's filtered down to just the failing test. Change the file extension to *.log and you can crunch it using `bunyan`.
