What I observe is that it's trying to do a pixel diff on dumpAsText tests. It obviously can't find the png and reports it as MISSING. Looking at the test, it's hard for me to see how it's possible that these tests would not hit the dumpAsText line. 

Also, notably, it's getting a JS exception saying that "debug" is not defined, which is defined in the same file as the dumpAsText call. So, sometimes that file isn't getting loaded. But the path is correct and most of the time it gets loaded fine.

In conclusion, my best guess is that Chrome/WebKit has a bug with script loading where we continue loading the page instead of blocking until the script has loaded. Not sure who the experts on html parsing / script loading are. CCing a few likely candidates. :)
