Resolution: Won't Fix
Nothing we can do I'm afraid, this is a UIWebView crash

> I have an infinite scrolling list in which the user scrolls to the bottom and new items load from the database. I am properly removing any object and image from the DOM however that is not in view. I unload images by setting their src to an empty string. I have monitored with Instruments on the Mac and I can see the memory constantly being collected and never peaking about 25 MB. My problem is random, when rendering a new page from infinite scrolling, if it is heavy with images, it crashes. Here is log from the thread that crashed:

> Images are about 900px width and resized with css to about 400px. There are no shadows or fancy css3 effects on the images.
> Every time the app crashes, it usually comes after a memory warning. I have reproduced this only after getting 3 memory warnings.
> I always get this same crash dump every time it crashes.
