That many images failed to Init does seem odd.

FWIW I saw this live while investigating bug 1219784.

This continues to be the most verbose warning during testing in imagelib.

It's also part of the noise during a normal startup of a debug build, that noise being annoying when trying to find the real cause of a mystery startup crash...

In case anyone has time to look at this again, I made the warning print out the URL of the image that caused the failure in bug 1265744.

Various URLs spewed from RasterImage::Init warnings.

Timothy, does this list in attachment 8755085 [details] help at all? FWIW in local testing I noticed this message when loading a page hosted locally, it was loading a fav.ico that didn't exist.

I just started mochitest and debugged the first of this warning that came up. It was because the mime type for the image was text/html. This is the mimetype after sniffing, so it's not just the mimetype being set incorrect for a valid image. We should silence the warning.

Comment on attachment 8755091 [details] [diff] [review] Remove RasterImage::Init failed warning Thanks.
