LOG_ERROR when attempting to create a sandbox extension

When trying to load any page, I get the following errors printed to the console (debug build):

Two of the errors (Caches/com.apple.Safari/WebKitCache/OfflineWebApplicationCache and Safari/Databases) continue logging while the page keeps reloading "due to an error".

I'm building off of r234441.

A lot of the time, "Could not create a sandbox extension" means that the directory doesn't exist, and that could be a bug with process spawning code in WebKit.

But this looks concerning:
