Version:            (using KDE 4.2.1)
Compiler:          GCC 4.3.3 (Gentoo 4.3.3 p1.0, pie-10.1.5)

When viewing a page that displays animated GIF images, the animations seem to just stop. There's a bit of movement for a few milliseconds, but then they just freeze.

In "Settings->Configure Konqueror->Web Browsing->Appearance->Animations" 
I have it set to "Enabled".

I'm on KDE 4.2.1/Qt 4.5.0 but Konqueror had the exact same problem in KDE 4.2.0 and KDE 4.1.3 with Qt 4.4.2 too.

If I right click on the image and select "View image", it opens in a new tab where the animation works correctly (even though it downloads the image again, totally disregarding the fact that it's in the cache already, but that's another issue).

I'm not providing a "test case" since the bug is there with all pages that have animated GIFs.
