The buildbot is showing a leak in BitmapImage::cacheFrame.
I assume this leak was caused by recent refactoring. It's pretty obvious from code inspection what it could be.

Comment on attachment 26886 [details] patch On re-reading the code, I'm not sure the patch is correct. It looks like the function should never be called if the frame is non-zero. So I'm clearing the review flag for now. I don't know how to explain the leak seen on the bot.
The leak isn't showing up any more. Maybe it was a false positive.
