WebView problem

Sorry for the cross-post, but I think this problem may not be exclusive
to webkit. In my application, I'm trying to load a WebView in the
background and grab a screenshot of it. To do this, I create a webview,
load it into an off-screen window, lock focus on it, call drawRect, then
create an NSBitmapImageRep from it. This works great for 99% of pages,
however occasionally I'll hit a page where it overloads the stack and
crashes my app (the stack has 10,000+ calls on it). This takes place
somewhere in the khtml renderer under WebKit, and I'm pretty sure it has
to do with WebKit trying to display an animated GIF offscreen. Has
anyone ever encountered an issue like this with WebView or any other
NSView doing off-screen drawing?
