Core dump. GtkLauncher, r152392, 64-bit DEBUG build

I just took a quick glance at this, and can confirm what Martin says in comment #8.

If you want to reproduce this in a debug build, using G_SLICE=debug-blocks and MALLOC_CHECK_=2 seems to trigger the X error almost instantly.

I tried with an even larger (in the number of frames) GIF, such as the one in https://bugzilla.mozilla.org/show_bug.cgi?id=523950, which has nearly 9000 frames, and got a segmentation fault instead of an X error: I am attaching a core file for that.

If you try gifs with less frames (100, for example), no error happens. Besides getting the core file, I haven't done any actual progress in the investigation, so feel free to work in this bug.
