1101808 - Mozchomp gif is corrupted

Status: RESOLVED DUPLICATE of bug 1101759

(Core :: Graphics: ImageLib, defect)

Description

[Daniel Holbert [:dholbert]]

STR:
 1. Visit https://bugzilla.mozilla.org/extensions/BMO/web/images/mozchomp.gif

Or, view this data URL with a <img> container:
data:text/html,<img src="https://bugzilla.mozilla.org/extensions/BMO/web/images/mozchomp.gif">

ACTUAL RESULTS: The first 1 or 2 frames display correctly, and then the GIF freezes on a corrupted image. (Bottom half is black, no animation). If you view the image directly, it animates in the *favicon*, but not in the actual page body.

This reproduces regardless of whether e10s is enabled.

which makes me suspect bug 1079653, which led me to dependent bug 1101759, which it looks like this is a dupe of.
