Backtrace

I hit this crash in the GTK minibrowser when going back from results.webkit.org/ to the LayoutTests results page.

It's hard to reproduce.

ASSERTION FAILED: m_compositorThread == &Thread::current()
../../Source/WebCore/platform/graphics/texmap/TextureMapperPlatformLayerProxy.cpp(65) : void WebCore::TextureMapperPlatformLayerProxy::activateOnCompositingThread(WebCore::TextureMapperPlatformLayerProxy::Compositor*, WebCore::TextureMapperLayer*)
