GIF animation drops all frames after a certain point
Some GIF images drop all frames after a certain point, causing them to restart prematurely. The regression range looks to be: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=be4b064f1159&tochange=5684f06138f3 From that list, the likely culprit is Bug 609499
Confirming. EXPECTED RESULTS: Chair spins, camera pans up/left to a woman's face. ACTUAL RESULTS: Chair only spins partway, & animation abruptly restarts. Firefox 5 shows EXPECTED RESULTS. Nightly shows ACTUAL RESULTS. (Nightly never gets to the part of the animation with the woman's face) Mozilla/5.0 (X11; Linux i686; rv:8.0a1) Gecko/20110806 Firefox/8.0a1

It's happening on Windows platform (win7 at least) also. Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0a1) Gecko/20110806 Firefox/8.0a1
Local track down using Linux x86_64: The first bad revision is: changeset: 73789:67044ea27b53 user: Joe Drew <firstname.lastname@example.org> date: Wed Aug 03 15:19:19 2011 -0400 summary: Bug 609499 - Some invalid GIF files don't terminate their LZW data with a 0-length block. Handle them better by handling them less specially. r=jrmuizel http://hg.mozilla.org/mozilla-central/rev/67044ea27b53
Here's another affected gif. Should show 2 people colliding, but Nightly just shows just a few frames of one person running at the beginning. (source: http://www.reddit.com/r/funny/comments/jjr70/smoosh/ )

joe, jeff, could you please take a look at this? We need to figure out whether we fix this or back out bug 609499 on Aurora, imo.
I've backed out 67044ea27b53 from FF8 (Aurora) and FF9 (Central): http://hg.mozilla.org/mozilla-central/rev/d2cd9f583b0a http://hg.mozilla.org/releases/mozilla-aurora/rev/b747b6535a03

Why is this bug still open? I think it can be marked as FIXED or WORKSFORME.
Since bug 609499 was backed out, this is no longer an issue.
