This seems to be fixed in firefox 7.0.1 (tested on 10.10/maverick with 7.0.1+build1+nobinonly-0ubuntu0.10.10.1~mfs1), but can be confirmed for eog 2.32.0-0ubuntu1.
The same symptoms can be observed when this and 2 other gifs are opened with google chrome 16.0.904.0, see http://code.google.com/p/chromium/issues/detail?id=100170 ** Bug watch added: code.google.com/p/chromium/issues #100170 http://code.google.com/p/chromium/issues/detail?id=100170 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/839251 Title: EOG and Firefox eat up memory when opening animated GIF Status in “firefox” package in Ubuntu: Incomplete Bug description: When trying to open a specific GIF file with either Firefox or EOG, the process eats up all the system memory (4GB in my case), so the system starts to swap and becomes unusable. According to the file(1) utility: evil-2336-6467_c39e.gif: GIF image data, version 89a, 20000 x 8880 Also, GIMP manages to open the file, showing 42 transparent frames of size 20000 x 8880, except the first frame, which is completely black. KolourPaint, the Windows Explorer and the Windows Internet Explorer display the file as a 44x44 pixel image, which I suppose is the correct size. However, also the GNOME file open dialog displayes the first frame from the file correctly.
