Thanks a lot for the patch, that did indeed solve the issue.

Just for good measure, checked my file association settings anyway,
and surprisingly enough, I had actually been using gvpart this
entire time. Not sure when and why I changed that. Yet, I couldn't
get *any* GIFs to render, no matter how many times I restarted
Konqueror or reloaded the page. Strange.
