This hasn't been forgotten; I just haven't had a chance to look into these yet.

That last crash message appears to be unrelated to the others. The first two appear to be from some kind of heap corruption, and from what I can tell they're happening in DeallocateUserList() or thereabouts.

The latter crash really is in iconToPixels() and thus has nothing to do with the other two. I believe this is related to an issue I'd seen with .gif and .jpeg files, and is probably a different icon type misbehaving when trying to read its dirs. I'm adding some sanity checks against that.
