Comment 5 for bug 1527315

The gif contains 491 frames at 960 by 540. Uncompressed, that's half a MB per frame, for a total of 254 MB. So, during scaling with gdk_pixbuf, we have at least this much in memory, plus a copy of the scaled result. Little wonder that things break.

I'll see if we can change things such that we extract a single frame and then scale that. (It's not a trivial change, so this will take a while.)
