Description Justin Lebar (not reading bugmail) 2012-01-26 16:55:22 PST
There must be a race condition here which causes us to fire either an onerror or an onload for this erroneous image depending on how much stuff we decode.

Review: JOEDREW
There's clearly a race here with respect to how much of this image we decode in one timeslice.
