Created attachment 262029 [details] Working image. This comment: https://github.com/kohler/gifsicle/issues/50#issuecomment-143871959 shows two 3-color, single-frame GIF images, 3840x1100 in size. The two images contain the same image data, encoded slightly differently. Both images are as far as I can tell valid GIFs, and they are both displayed correctly by Chrome and Firefox. But Safari and Webkit nightly (r190281) treat the first image as broken. I'm attaching the images too.

Thank you for the report! This image fails to open not just in Safari, but also in Preview.app. As such, this is an issue in lower level system framework, not in WebKit. I have moved it to Apple internal bug tracker for investigation. Closing as INVALID as a non-WebKit bug.

This should work properly in OS X 10.11 El Capitan. Thank you again for the report!
