If you press the 'show all bookmarks' button whilst this page is loading, Safari/WebKit r17434 crashes with the following backtrace... Thread 0 Crashed: 0 com.apple.WebCore 0x011c4e78 WebCore::RenderObject::setStyle(WebCore::RenderStyle*) + 2056 1 com.apple.WebCore 0x0119bbb8 WebCore::RenderBox::setStyle(WebCore::RenderStyle*) + 40 2 com.apple.WebCore 0x011923d8 WebCore::RenderBlock::setStyle(WebCore::RenderStyle*) + 88 3 com.apple.WebCore 0x012828bc WebCore::Node::createRendererIfNeeded() + 268 4 com.apple.WebCore 0x012879d0 WebCore::Element::attach() + 32 5 com.apple.WebCore 0x01133340 WebCore::ContainerNode::appendChild(WTF::PassRefPtr<WebCore::Node>, int&) + 544 6 com.apple.WebCore 0x011279b0 WebCore::Document::implicitClose() + 320 ...
