The files in WebKit/chromium/src/js/Images/ should not be executable. svn propdel svn:executable WebKit/chromium/src/js/Images/* should probably do the trick.
Evan, does this affect the images in WebCore/inspector/front-end/Images/ or only the Images on the Chromium port? Anyone have a Subversion checkout these days?
This only affects the files in WebKit/chromium/src/js. I'll fix this.
