SUMMARY:

I hit this assertion twice while fooling around on the projector at the WebKit Contributors MEeting.

STEPS TO REPRODUCE:

 * Use a debug build.
 * maps.google.com
 * Click the hamburger menu next to search bar
 * Select "Earth" to turn on satellite imagery
 * zoom in and out, pan around until it crashes

STACK TRACE:

ASSERTION FAILED: !resources.get(key)
