Bug 17686 regressed with the libpr0n landing, because libpr0n doesn't check the pres shell's GetImageAnimationMode(). Here's how it was called in the old imglib: http://lxr.mozilla.org/seamonkey/source/modules/libimg/src/if.cpp#1833 which was called from IL_GetImage on line 1918 of the same file. I can add the call to libpr0n if you point me in the right direction (perhaps in imgContainer::Init or imgContainer::StartAnimation?)
Added a small test case in the url field.
This seems to be the same as bug 74169. Please ... ;-)
